I've been using GolfShot for months and never had a GIR issue so not quite sure what you mean by that? It goes off of what you put into it, so if its a par four and you enter a score of "4" with 2 putts, it assigns you the GIR. Am I missing something??
I've been hesitant to pull the trigger on GolfScape due to some bad reviews I've read on it. Most of them focus on the inability to see the screen in bright, sunny conditions. Do you ever have this problem with it??
