I recently started doing this. I heard about it again on the Hack It Out podcast with Sasho Mackenzie. He was talking about the pros and cons and how to implement it. I’ve played three rounds doing it so far. In those three rounds, I gained 0.3, 1.6 and lost 1.6 vs pga tour. My last twenty rounds I’m at -1.3 strokes average so based on a very small sample I have improved from it. Those three rounds are tournament rounds too.
Has anyone else experimented? I’ve been doing it for shorter putts so far. It feels weird to look at the hole for long putts so I haven’t yet. I think eventually I will do so, but I need to get comfortable on the putting green first.
I did do this for a spell a few years ago but I stopped for some reason. Probably I felt silly doing it. Now I care less about stuff like that so if it continues to work I’m going to continue to do it. There definitely are benefits to it. Change of focus from mechanics and the loss of need to remember how far you want to hit it strike me as the obvious ones.
