I don't know about TOTALLY irrelevant Wulsy. It depends what you're asking about, but if average GIR hasn't changed all that much in 50 years, I'd be tempted to conclude that there's some continuity.
The difficulty I see (and it's a variation on Kevin and ej20's points) is that on tour, players tend to bunch in the 11 - 13 GIRs range. Given that many of the statistical "missed greens" will be good shots to the fringe, and that a proportion of GIR will result in 3-putts, it's easy to see how the GIR stat doesn't discriminate very well between players at that level. You need a different slice of information to determine where players at that level gain an edge against the field.
