I have posted the same subject a few weeks ago after I became "master". My putting has gone to hell. Luckyman, I have the same leaves you are having, 2"-1.7ft. FOREVER!
I'm missing <3ft putts a a very regular basis. It's embarrassing now to play skins. I've missed 2,5ft putts with the green dots standing still, it either stops short 2" in front or either side. It comes to the point that I have no idea what to do on short putts anymore. Every putt is bye-bye birdie.
Here's an interesting wonderment yesterday, I made a 150ft eagle putt...go figure.
I wish an improvement for the both of us, but It still ain't happnin.
