Overkill has both of the tools you mentioned. He can tell you about that. I tried some of that, but I found it difficult to trust my notes (not SURE that this was the exact line I rolled balls on before).
But... I am a very intuitive putter....and a good one. The main thing I want to know is whether the greens act like I read them. Before I roll, I read the putt. If it does what I think it should, then I am happy. Then I try to find some that don't and make a note. Usually it would be more break than I see rather than breaking the other way.
I think that great putters see more detail than the rest of us.
