I looked at my 3 lowest rounds this summer, two 81's and an 82 (all at my home courses).
The round of 82 (East course) I had 4 GIR, 9 pars, 29 putts.(one double, the rest bogeys)
The round of 81 (East course) I had 6 GIR, 8 pars, 32 putts (the rest bogeys)
The round of 81 (West course) I had 5 GIR, 1 birdie, 9 pars, 29 putts (the rest bogeys)
So the West course is approx. 120 yards longer overall from the forward tees. I've noticed before that to go in the low 80's for me, since I don't get a lot of GIR, I have to have less than 31 putts, in general. I don't measure proximity to the hole, but you could theorize that despite not having the GIR, my putts may not be overly long (as a whole) because I'm hitting my approach shot with a wedge, so I put myself in to position to get the one-putt.
