First let me say that I am an average putter.
I am also Jekyll 'n Hyde when it comes to the different play formats, i.e. Match or Alt Sht and strokeplay. In strokeplay i am awful, simply awful, but can be brilliant in A Shot.
So I am for the next 2 weeks gonna keep a list of all missed putts length only, but categorise them into Match play and stroke.
The total footage will be massive I am sure.
If anyone else wants to try and do similar and post their results here I am sure it would make interesting analysis.
I wanna be a better putter. I do practice but it does not seem to help.
The theory is that it is a mental thing
