7 iron vs 8 iron distance
At tour speed a 7 iron carries about 172 yards and a 8 iron about 160 yards, a gap of 12 yards on the published table. For a 15 handicap the gap is 9 yards: 136 yards against 127 yards. They sit next to each other in the bag, so the gap is the band of yardages between two full swings.
At tour speed
The 7 iron row is 90 mph, 120 mph of ball speed and 172 yards of carry; the 8 iron row is 87 mph, 115 mph and 160 yards. Roll is 4 percent of carry for the 7 iron and 4 percent for the 8 iron on a fairway landing, so the total gap is 12 yards.
By handicap
Both clubs at each handicap step on the handicap model. The gap narrows a little as speed falls, because the shorter club loses fewer yards per mile per hour.

What the gap means
A gap of 9 yards at 15 handicap means every yardage inside it is a shot for neither full swing: the 8 iron needs more than it has and the 7 iron needs less. That is a normal gap, and the cost inside it is small: the published fairway table moves only 0.02 of a stroke across half of it. The free launch monitor analyzer reads a session in the browser and flags gaps over 20 yards.
Distance decides less than the pattern around it. Two clubs that carry the same number can spread very differently, and the spread decides whether a target is safe; PinFlag measures the spread from your launch monitor sessions and your logged shots and draws it on the hole.
In PinFlag
Import a session and both clubs become Measured patterns in PinFlag: on the course the aim is priced with the pattern of the club in hand, and switching clubs redraws Shot Cloud with the other pattern around the same target, so the comparison is between two real spreads on the real hole, not two yardages.
