WHAT TO HIT NEXT

24 tasks · ranked by information gain

Generated from the ledger, not written by hand. Every task carries the numbers that put it on the list and the condition that takes it off, so hitting the shots retires it on the next pnpm ingest.

Ranked by what each bucket of balls would tell you, not by how few shots it takes. A club with four shots on file is not a noisy measurement — it is a blind spot, and the gaps either side of it are invisible rather than merely wide.

  1. 01

    The 3 Hybrid has never been measured

    blind spot
    why
    Callaway UW is in the bag at 19° and has not one shot on file across 8 sessions. Both gaps beside it are guesses about a club nobody has hit at a monitor. AutoShot has meanwhile heard 23 full swings with it on the course — median 220 yd point-to-point — a number to check the monitor against, not a substitute for it.
    do
    Hit 21 in one block, the same as any other club.
    done
    15 usable shots with the 3 Hybrid.
  2. 02

    The 3 Iron has never been measured

    blind spot
    why
    TaylorMade P790 (2021) is in the bag at 19° and has not one shot on file across 8 sessions. Both gaps beside it are guesses about a club nobody has hit at a monitor.
    do
    Hit 21 in one block, the same as any other club.
    done
    15 usable shots with the 3 Iron.
  3. 03

    The 4 Iron has never been measured

    blind spot
    why
    TaylorMade P790 (2021) is in the bag at 21° and has not one shot on file across 8 sessions. Both gaps beside it are guesses about a club nobody has hit at a monitor.
    do
    Hit 21 in one block, the same as any other club.
    done
    15 usable shots with the 4 Iron.
  4. 04

    The Lob Wedge has never been measured

    blind spot
    why
    Titleist Vokey is in the bag at 58° and has not one shot on file across 8 sessions. Both gaps beside it are guesses about a club nobody has hit at a monitor.
    do
    Hit 21 in one block, the same as any other club.
    done
    15 usable shots with the Lob Wedge.
  5. 05

    Nothing is measured above 195 yd

    blind spot
    why
    5 Iron at 195 yd is the longest club with enough data. Driver is in the ledger but below the threshold, so every gap above 195 yd is invisible — not wide, invisible. AutoShot has meanwhile heard 38 full swings with it on the course — median 252 yd point-to-point — a number to check the monitor against, not a substitute for it.
    do
    Hit 20 each of Driver, plus anything else you carry longer than a 5 Iron.
    done
    Every club longer than the 5 Iron has 15+ usable shots.
  6. 06

    Measure the Driver

    coverage
    why
    0 usable shots of 1 hit. Below 15, so it is suppressed and both gaps beside it read "not shown". AutoShot has meanwhile heard 38 full swings with it on the course — median 252 yd point-to-point — a number to check the monitor against, not a substitute for it.
    do
    Hit about 21 in one block — 15 more usable, plus 3 warmup and a mishit or two.
    done
    15 usable shots.
  7. 07

    Settle what the Pitching Wedge actually carries

    consistency
    why
    Measured across 3 sessions whose medians differ by 16.8 yd. Its band is partly day-to-day drift, so the median is an average of two different versions of you.
    do
    Hit 20 in a single session, full swings only, and don't mix partial shots into the block.
    done
    Two sessions agree within 10 yd.
  8. 08

    Settle what the 8 Iron actually carries

    consistency
    why
    Measured across 2 sessions whose medians differ by 14.1 yd. Its band is partly day-to-day drift, so the median is an average of two different versions of you.
    do
    Hit 20 in a single session, full swings only, and don't mix partial shots into the block.
    done
    Two sessions agree within 10 yd.
  9. 09

    31.1 yd hole between 5 Iron and 6 Iron

    gapping
    why
    Their medians are 31.1 yd apart. Any shot landing in that window needs a swing you have not measured.
    do
    Build a repeatable partial 5 Iron for the middle of the gap, measure it as its own block, and label the block in data/wedge-blocks.json so the matrix can retire this.
    done
    A measured shot type covers the middle of the window.
  10. 10

    Settle what the Sand Wedge actually carries

    consistency
    why
    Measured across 2 sessions whose medians differ by 10.8 yd. Its band is partly day-to-day drift, so the median is an average of two different versions of you.
    do
    Hit 20 in a single session, full swings only, and don't mix partial shots into the block.
    done
    Two sessions agree within 10 yd.
  11. 11

    Settle what the 6 Iron actually carries

    consistency
    why
    Measured across 3 sessions whose medians differ by 10.3 yd. Its band is partly day-to-day drift, so the median is an average of two different versions of you.
    do
    Hit 20 in a single session, full swings only, and don't mix partial shots into the block.
    done
    Two sessions agree within 10 yd.
  12. 12

    A three-putt every 7 holes

    scoring
    why
    369 of 2717 recorded holes took three or more putts, and the 140 rounds that logged putting average 35.7 putts — the largest single line item in the score, and the only one the scorecards alone can see. The last 18 months say the same thing: one in 9 over 180 recent holes. The R50 screen agrees: 11 three-putts in 108 sim holes (one in 10).
    do
    Lag drill before every round: ten putts from 30+ feet, scored by finishing inside a flagstick's length, not by holing anything.
    done
    A capture with three-putts under one hole in 10.
  13. 13

    Par 3s are the screen's leak

    scoring
    why
    Over 38 par-3 holes on the R50 screen the scoring runs +0.76 a hole, against +0.32 across 19 par 5s — and a par 3 is nothing but one iron and the putter. Screen numbers: the launch is measured, the flight is modelled, so this speaks about club delivery, not wind.
    do
    An iron-precision block played as nine screen par 3s: three flags between 150 and 200 yd, scored by finishing inside ten yards of the flag — not by contact.
    done
    A capture whose screen par-3 mean sits within 0.3 strokes-over-par of the par-5 mean.
  14. 14

    6 of 6 wedge-matrix cells have never been measured

    wedge matrix
    why
    Every measured wedge has a full-swing number and nothing below it: Pitching Wedge (half, three-quarter), Gap Wedge (half, three-quarter), Sand Wedge (half, three-quarter). Between a full wedge and a chip lives most of the scoring window, and the ledger cannot see a partial's length — only a labeled block can say what a half swing carries.
    do
    Pick one wedge and one length. Call the carry before every swing, hit about 13 in a single block, then record the block in data/wedge-blocks.json — session, club, swing, first and last shot time. Unlabeled, the block buys nothing.
    done
    Every partial cell of a measured wedge holds at least one labeled block.
  15. 15

    The 5 Iron finishes 18 yd right

    consistency
    why
    Median miss +17.6 yd, 80% band 38 yd wide — but from a single session, so this may be one bad day rather than a tendency.
    do
    Hit 20 more on a different day before reading anything into it.
    done
    A second session confirms or clears it.
  16. 16

    The 7 Iron finishes 14 yd right

    consistency
    why
    Median miss +14.0 yd, 80% band 38 yd wide — but from a single session, so this may be one bad day rather than a tendency.
    do
    Hit 20 more on a different day before reading anything into it.
    done
    A second session confirms or clears it.
  17. 17

    23.5 yd hole between Pitching Wedge and Gap Wedge

    gapping
    why
    Their medians are 23.5 yd apart. Any shot landing in that window needs a swing you have not measured.
    do
    Build a repeatable partial Pitching Wedge for the middle of the gap, measure it as its own block, and label the block in data/wedge-blocks.json so the matrix can retire this.
    done
    A measured shot type covers the middle of the window.
  18. 18

    The 6 Iron finishes 12 yd right

    consistency
    why
    Median miss +11.5 yd, 80% band 32 yd wide across sessions that agree, so it is a tendency rather than a bad day.
    do
    Worth a lesson or a face-to-path check — the number is consistent enough to be real.
    done
    Median miss inside 8 yd of the target line.
  19. 19

    18.4 yd hole between 8 Iron and 9 Iron

    gapping
    why
    Their medians are 18.4 yd apart. Any shot landing in that window needs a swing you have not measured.
    do
    Build a repeatable partial 8 Iron for the middle of the gap, measure it as its own block, and label the block in data/wedge-blocks.json so the matrix can retire this.
    done
    A measured shot type covers the middle of the window.
  20. 20

    16.5 yd hole between 9 Iron and Pitching Wedge

    gapping
    why
    Their medians are 16.5 yd apart. Any shot landing in that window needs a swing you have not measured.
    do
    Build a repeatable partial 9 Iron for the middle of the gap, measure it as its own block, and label the block in data/wedge-blocks.json so the matrix can retire this.
    done
    A measured shot type covers the middle of the window.
  21. 21

    No club data on 46 of 301 shots

    data
    why
    2026-07-02, 2026-08-02 recorded the ball but not the club — smash factor and club speed are both missing. Those shots skip the smash-based mishit test, so part of the ledger is filtered more loosely than the rest.
    do
    Check the club tracking sticker and the monitor's placement before the next session — club speed, smash, attack angle and path all depend on it.
    done
    New sessions record club data.
  22. 22

    6 Iron and 7 Iron do the same job

    gapping
    why
    Only 4.1 yd apart. One of the two is redundant, which is where a hole elsewhere in the bag comes from. The bag has them 4.0° apart, so they were built to be different clubs.
    do
    The heads are not the problem — hit them back to back in one block and watch the strike on the 6 Iron.
    done
    The two sit more than 8 yd apart, or one leaves the bag.
  23. 23

    7 Iron and 8 Iron do the same job

    gapping
    why
    Only 2.7 yd apart. One of the two is redundant, which is where a hole elsewhere in the bag comes from. The bag has them 4.5° apart, so they were built to be different clubs.
    do
    The heads are not the problem — hit them back to back in one block and watch the strike on the 7 Iron.
    done
    The two sit more than 8 yd apart, or one leaves the bag.
  24. 24

    Gap Wedge and Sand Wedge do the same job

    gapping
    why
    Only 6.7 yd apart. One of the two is redundant, which is where a hole elsewhere in the bag comes from. The bag has them 4.0° apart, so they were built to be different clubs.
    do
    The heads are not the problem — hit them back to back in one block and watch the strike on the Gap Wedge.
    done
    The two sit more than 8 yd apart, or one leaves the bag.

The weeks

Every committed week of goals (data/goals.json), measured in record time — did the number move. The current week renders on the front page; this is the history.

  • 2026-09-16open: One more round with the watch on. At 5 the short-game and lie findings switch on and the number that matters most gets printed: 0 up-and-downs in 33 chances over the 4 rounds heard so far (Harding 08-20, Presidio 08-22 and 09-08, Olympic Lake 09-15). · open: Carried from 09-09, still 0 swings on file. It started 15 holes over the 4 watch rounds and 3 of those tee shots went under 65 yd. The block is a contact block first and a yardage block second: 15 usable swings, low point in front of the ball, the R50 keeps score.
  • 2026-09-09open: One R50 block, 15+ usable 3 Hybrid swings. It started 7 of 18 holes at Presidio on 09-08 (221 yd median on the course) and has no monitor number — the most-used unmeasured club in the bag. · open: Two 20-minute lag-speed sessions (20/30/40 ft ladder, every first putt inside 3 ft) and one round with at most one three-putt. Speed, not line: 80% of amateur three-putts start with a first putt more than 5 ft short or long.
