It isn't just the putting. Everything is less consistent, approach shot distance, wind effect, etc. My avg approach put me within 15ft, now I am well outside that. My avg greens in regulation was 80%. Now I'm lucky if it is 60. Also, and this may be the issue, it seems like the swing bar speed is inconsistent, so it is more difficult to "ding". In the past, even if I was just a tad either side of the "ding" the variation would be minor. Now the shot result is as if I missed it by half an inch. I don't want to whine about it, but I would swear that something outside my control has changed.
