The shooter ID error has already been corrected. But for interests sake, this is Anthony Matarese...

Seems like a lot of the top sporting clays shooters are very forward on the gun, with their noses just about at their knuckles. A stark contrast from Kim Rhode being well beyond the old "2-3 finger spacing" guideline. I don't know if Kim is just the oddball, or if that has something to do with the different games dictating a different style.
Shotgun "fit" is as much an art as a science, I think. Matching shooting style to individual anatomy and all the available stock dimensions (cast, drop, pitch, grip, etc.) introduces an endless combination of variables. I would agree that different gun fitters might come up with different dimensions for the same shooter, although the differences should be minimal unless the shooter changed their style or gained/lost a lot of weight between fittings. And as falconflyer pointed out, unless your mount is 100% consistent then a professional gun fitting is a waste of time.
I would disagree with Don Currie's opinion that LOP is the most important dimension. It is by far the easiest to adjust, but my own experience and certainly the photos of top shooters we've seen here would indicate LOP is not so critical. I would quickly qualify that by saying you can get used to a particular LOP and shoot it well, but find a change difficult. That was eluded to by another comment here and my own experience support this. I'm 6'4" and grew up shooting a Win Model 12 that was about 13.5" LOP, then eventually an 870 at 13.75". I shot the 870 for a very long time and because I didn't know any different I just made my body/shooting style fit it and I shot it very well. I shot other guns of "average" LOP fine as well. Only about 5 years ago (after 30+ years of shooting) I started getting quite interested in sporting clays and have since been exposed to some "good" shooters and a few guys who knew a little about stock fit. I was told my 870 stock was far too short and as I started shooting better and moving to different guns I've now come to realize my most comfortable LOP is really about 15.25-15.5" depending on the gun and time of year (i.e. thickness of clothing). I hope to get a gun fitting someday, just to see how it might feel to have all the other minutiae tweaked.
Stock fit is definitely a complicated topic, although "close enough" works "OK" for all but the highest performing shooters.
