A standardized test that doesn't change between sessions — so the gap between this Tuesday and three Tuesdays from now is signal, not noise.
Every Combine evaluates the five places putting actually breaks: start line, aim, contact, speed, and read. Same scoring thresholds every Combine. Same five sub-scores out of 100. The number you finish with is comparable to the one you finished with three weeks ago — not because the green was the same, but because the test was.
Start line, aim, contact get sorted out.
Speed control gets honest.
Read and speed under load.
The app guides setup. If your green can't offer break in both directions, it records the asymmetry and doesn't penalize you for what the green couldn't give you.
Overall score, 0–100. Five sub-scores, each color-coded — Strong / OK / Needs work. The biggest leak named in coaching language ("under-reading right-to-left breakers"). Up to three miss tendencies pulled from the per-putt diagnostics across all 18 putts. One or two recommended drills, prioritized by the leak. And — if you've taken three before — the impact this Combine just had on your Putting Handicap.
The Combine isn't lab-grade. Your green isn't a USGA stimp 11. The score on a faster green will run two or three points lower than the same skill on a slower one. Comparing your number to a Tour pro's misses the point — the Combine is built to compare you to you. Six weeks of Combines on the same green is where the signal lives. Not the absolute number on Tuesday.
Eighteen real putts. The full diagnostic. No card.
