Sample Divot Card
Low-right / low-fade pattern
Today's focus
18-minute 8-Iron Reset
A short block that narrows start line first, then checks face control, then checks strike/low point.

Matched stock 8-ironsWhat changed
- Dispersion increased versus the saved 8-iron baseline.
- Right-miss rate climbed from 24% to 42%.
- Launch and spin are slightly below the player baseline.
- Carry distance stayed close enough that this is a pattern card, not a speed card.
Why we think this
- The same club, target, and shot type create a repeatable miss cluster.
- The miss direction, launch, and spin moved together instead of appearing as one-off outliers.
- The retest should be measurable with the same target and 20 stock 8-irons.
Cause hypothesisLikely, not certain
- Face may be delivered slightly open to the target or path on stock 8-irons.
- Low point or strike quality may be reducing launch and spin.
- Target alignment could be drifting right if the simulator start line is not recalibrated.
More drill options2 alternatives
Toe-Up Face Drill
Alternate rehearsal swings and stock shots until the curve window stabilizes.
Low-point / strike control
Keep launch and spin from dipping while the start line tightens.
Retest planHow to prove it moved
20 stock 8-irons to the same target
- 1Use the same simulator, target line, ball type, and stock swing intent.
- 2Remove obvious misreads, but keep normal misses in the sample.
- 3Upload the retest as a matched 8-iron session.
Pass / fail criteria
- Offline average improves below the target window.
- Right-miss rate drops under 28%.
- Launch and spin return within the baseline band without losing carry.
Not today's focusKeep the block narrow
- Do not chase more club speed in this block.
- Do not rebuild the full swing from this data alone.
- Do not assume an exact swing fault without strike data or coach review.
Coach-style note
The ball-flight pattern is clear enough to practice, but the exact mechanical cause should stay a hypothesis until a coach or impact evidence validates it.
Demo card. Launch-monitor data can identify patterns and confidence levels, but it does not prove exact swing mechanics by itself.
