They don't "keep" stats on Par 5 courses, Par 3, Best of courses, or Custom Courses....so it doesn't matter, they don't affect your stats anyway....
Also as was mentioned, any drive with any club other than the Driver isn't included in one's driving stat....the pay courses were notorious for this error.....
While I know those courses don't affect average, the par 3s and 5s have always affected my stats. It's also my understanding that custom courses also count for stats. Indeed, in the FAQ, it says "other stats will be saved."
And I believe they fixed the problem with using other clubs off the tee and the driving accuracy stat. For the practice round I played, it recorded my stats accurately, even though I only used a driver once.
