There is a prescription that has been kicked around for years which relates number of GIRs to score you should have shot. The equation goes like what you said only 95. Let's say you had 8 GIRs. Then you should have shot 95 - 2*8 = 79. If you shot more than a 79 then you either had penalty strokes (need to work on the long game) or you had 3-putts, chili-dips, etc... (need to work on the short game). Mostly this prescription is used as a way to determine if you need short game help or not.

I played a round the other day and shot 81 with 4 GIRs. As you can see, my short game was outstanding that day! I have also hit 13 GIRs and shot 74 (ooops). In general, it is not a bad rule of thumb and makes for interesting conversation after the round is over.
