Mostly I use 3 shot groups. That way I can avoid the 5th shot gremlin. I’ll mess up that 5th shot regularly. Makes me crazy.
I never could make short putts for money either.
Kinda like the old saying 3 shots proves the load, 4th shot proves the gun, 5th shot proves the shooter. And yes #5 can be a real irritant. BTDT 😁
