Claude pose-tracked the swing frame by frame, found the fault at the top — and prescribed one drill to fix it. Then check your own pump at the bottom.
Backswing in real time — tap to replay
“Speed isn’t the problem. The rushed, over-long top is — and it costs you the slot.”
The slot is the delivery lane: on the way down, the shaft drops slightly behind your hands onto a shallower plane, so the club attacks the ball from the inside.
Same top position. Two totally different deliveries.
Here’s the chain: rush the backswing, and the club drifts past parallel. From there the only recovery is throwing the club over the top — steep, outside-in, pulls and weak cuts.
A patient top that stops at parallel gives the club time to fall into the slot instead.
The pump drill isolates the transition — the half-second where the slot is won or lost — and lets you feel it twice before you ever swing at the ball.
Each pump grooves three things at once: a top that stops at parallel, a first move down into the squat, and the shaft shallowing behind the hands instead of lunging over the top.
No ball. No rush. Just the slot, on repeat — until the third move is a strike.
The move on loop — watch the shaft fall into the slot
Slow count back. Shaft stops at parallel, not past it. Hold one beat.
Drop hands to lead-arm-parallel. Feel the squat load and the shaft fall behind the hands — that’s the slot.
Same drop, same feel. Twice in the slot, zero rush.
No rebuild, no reset — from the second pump, go. The strike inherits the slot.
Five unannounced swings on camera — every backswing ≥ 0.75s
4 of 5 tops at parallel — not past it
The slot shows up without thinking about it
Film your pump drill (down-the-line, phone at hip height), drop it here, and grade yourself with the same criteria the AI used. Video never leaves your phone.
Play in slow-mo. Tap TAKEAWAY the frame the club starts back, then TOP when it stops. We do the math off the video clock — slow-mo doesn’t cheat it.
Scrub to your top and your pump. Be honest — the camera already knows.
Shaft stops at parallel at the top — not past it
Pump drops hands to lead-arm-parallel (P5), not just a wiggle
Shaft falls behind the hands on the pump — shallower, not steeper
Lower body squats into the drop — pressure left, chest stays back
