Golf at 75 mph swing speed

A driver swung at 75 mph carries about 173 yards and totals 187 yards on the published tour table, with 105 mph of ball speed at a smash factor of 1.40. At the same fraction of tour speed a 7 iron carries 109 yards. The speed maps to about a 33 handicap on the handicap model and beyond the oldest band on the age model; 5 mph more is worth about 13 yards of carry.

Driver at 75 mph

Ball speed is club head speed multiplied by smash factor: 75 multiplied by 1.40 is 105 mph. Carry is ball speed multiplied by 1.65 yards per mile per hour, the driver’s ratio from the published tour row: 173 yards. Roll adds 8 percent on a fairway landing, for 187 yards total. The smash factor sits below the tour value of 1.48 because the model eases strike quality by 0.01 for every 5 mph below the tour speed of 113 mph.

Every club at 75 mph

A golfer who swings a driver at 75 mph swings every club at 66 percent of its tour speed on the model, which is the fraction the table applies.

Where 75 mph sits

The handicap model puts a scratch driver at 106 mph and takes 0.95 mph off per stroke, so 75 mph is about a 33 handicap on the handicap model. The age model anchors 92 mph to a 15 handicap at 30 and eases 0.35 mph a year after that, so 75 mph is beyond the oldest band on the age model. Both are models of the average; the spread around the speed is where handicaps actually differ.

Five mph more

At 80 mph the driver carries 186 yards, 13 yards more. On a 400 yard par 4 that turns a 213 yards approach into a 199 yards one, which the published fairway table prices at 0.09 of a stroke before the iron is struck.

Speed against accuracy

Speed is worth strokes only when the ball stays in play. A drive into the rough costs about 0.25 of a stroke against the fairway at 150 yards on the published table, roughly what fifteen yards of carry buys back, and a penalty costs close to two. The number that decides a tee shot is the dispersion around the speed, drawn on the hole.

In PinFlag

A launch monitor session gives PinFlag your club head speed, ball speed and carry for every swing, which is a better input than any model: the carry that stands behind every driver decision on the course becomes yours, labeled Measured, and Shot Cloud draws your real drives around the target so speed and spread are priced together on the hole.
