Interesting. You certainly can see how course familiarity makes a difference......but at 4.7 rating points, it is only about 1/2 a throw per round (1 per day, 2 per 4 round tournament).
That really is almost imperceptible. And, I would think since ratings change by a good percentage of that variation every ratings change for many people, the margin of error of that data cuts into the meaningfulness of it too a bit.
But, I suppose the average is made up by people whose differences of playing home vs away are larger than that and some that are the reverse of that.
