WHAT TO HIT NEXT

21 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 7 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 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 7 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 7 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 7 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.
    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".
    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, and measure it as its own block.
    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

    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.
  13. 13

    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.
  14. 14

    The Gap Wedge finishes 8 yd left

    consistency
    why
    Median miss -8.4 yd, 80% band 10 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.
  15. 15

    24.1 yd hole between Pitching Wedge and Gap Wedge

    gapping
    why
    Their medians are 24.1 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, and measure it as its own block.
    done
    A measured shot type covers the middle of the window.
  16. 16

    22.7 yd hole between 8 Iron and 9 Iron

    gapping
    why
    Their medians are 22.7 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, and measure it as its own block.
    done
    A measured shot type covers the middle of the window.
  17. 17

    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.
  18. 18

    No club data on 46 of 255 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.
  19. 19

    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.
  20. 20

    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.
  21. 21

    Gap Wedge and Sand Wedge do the same job

    gapping
    why
    Only 6.1 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 Gap Wedge.
    done
    The two sit more than 8 yd apart, or one leaves the bag.

What the categories mean

blind spot
a gap that cannot be seen at all until something is measured
coverage
a club below the 15-shot threshold, so it is suppressed
consistency
a number that moves between sessions, or a miss that repeats
gapping
a distance problem the chart has already confirmed
data
a metric the monitor did not record
