Reproducing the conditions of yesteryear is, to me, time wasted. As some have noted, nappy cloths and lousy pool balls were standard back then, rail rubber was less consistent, low deflection shafts didn't even exist yet, pool rooms were hot and smoky, etc., etc., etc.
How many AZers recall that, in pro baseball, the pitcher's mound was lowered in the late 1960's? Does that mean that we cannot compare the hitters and pitchers of today with those of yesteryear? No, it doesn't. Baseball has evolved and is different today than in the past, but players, fans, and sports journalists all delight in comparing the stats across the generations, despite the fact they understand how much has changed about the game.
Mosconi was the best of his era and owns the highest exhibition run in history (as already mentioned, Cranfield ran 768 in practice). In the exhibitions at the Riviera, noone beat Mosconi, but Willie's record will fall one day. Schmidt, Hohmann, Harriman, Appleton, Ortmann, and a few others have it in them to beat Willie's highest exhibition run, and I wish them good luck in doing so.
The difficulty of comparing players across generations has been discussed often here on the forum. Nonetheless, I feel that trying to reproduce the playing conditions of the past to facilitate such comparison is going overboard.
