I just look at my skycaddie and it tells me what I need to know putt wise. I also just look back over my round for my own stats.
I'm not usually one to get hung up about stats as I quite often find that days I hit 9 fairways I shoot 72 for instance and other days I hit 14 fairways I walk off with 76 for example.
A bounce or a "rub of the green" can be more damaging to your round than a 3 putt or a missed firway in my experience so I dont generally get too hung up about round stats.
