Every green is solvable.
Green reading feels like art. It's arithmetic. Three numbers — slope, speed, distance — fix the line before you ever pull the trigger. Watch the "art" turn into a solved equation.
Give me three numbers. I'll give you the exact line.
Set the slope, the green speed, and the distance. The engine solves for the one aim that holes it — the amber line — and tells you how far outside the hole to start it. Then try aiming straight at the cup and watch what the green does to you.
Your feet already measured the slope. Your hand can aim it.
Stand between ball and hole and your feet feel the tilt as a percent. Hold your fingers at arm's length and each finger covers almost exactly one percent of slope. This is "AimPoint Express," and it's just the same geometry your feet already solved.
Three numbers beat twenty years of "feel."
Slope is the whole read
Gravity does the curving. Everything else is a modifier on it.
Speed sets how much it breaks
You can't read a line without committing to a pace.
Distance scales the aim
Same slope, longer putt, more inches of break.
Always miss on the high side
The pro side keeps the hole in play; the low side never had it.
Reading starts with knowing your speed.
You can't solve a break without a pace, and you can't own a pace without reps. Your PrimePutt rolls at a true Stimp 10 — the reference speed every read on this page is solved against.
