Smash factor is ball speed ÷ club speed. It’s the number that tells you how much of your swing actually reaches the ball — and where it’s leaking out.
Here’s mine, verified on a launch monitor. Long irons are near the ceiling for the club. Scoring clubs are bleeding.
Tap to replay — the leak is at the bottom of the bag
“120 mph doesn’t matter if only 1.14 of it shows up on a wedge.”
Smash factor caps out around 1.50 with a driver and drops naturally as loft goes up — more loft means more spin and less forward energy. So a lower wedge number is normal. Falling off a cliff is not.
A big drop at one club means one of three things: you’re missing the center of the face, hitting turf before ball, or delivering the club with the face open and adding loft. All three are strike problems, not speed problems.
Speed you can’t deliver isn’t speed.
Foot spray, face tape, whatever. Find out where you’re actually hitting it before you change anything.
Most heel patterns come from standing up out of the shot — the squat problem again.
Pressure forward, divot after the ball. That’s the line drill.
Chasing smash on five clubs at once teaches you nothing. Fix the worst one.
No club drops more than 0.04 from the one above it
Strike pattern is centered on the face, not heel or low
Same numbers hold on a second session, different day
Punch in whatever numbers you have from a launch monitor, a sim bay, or a Trackman session. You don’t need all five — two clubs is enough to see the drop. Nothing gets saved or sent anywhere.
Club speed and ball speed in mph. Leave a row blank if you don’t have it.
