One more factor in comparing the speed of play at RG and Forest Hills is is the pressure of the balls.

Did we have a discussion somewhere about the pressure of the balls used at Forest Hills?
This was in Sports Illustrated after 1981 RG:
No U.S. player has won in France since Tony Trabert in 1955, and no U.S. player seems about to, either. Jimmy Connors and John McEnroe may be 2-3 in the world, but not when they're playing on the irritating, slow and swirling clay of Paris with rocklike low-pressure balls. The low, flat trajectory of Connors' shots doesn't allow him the margin for error one needs in these brain-jangling, hour-upon-hour marathons. In such matches his aggression comes a cropper. The more facile McEnroe, blessed with marvelous touch on the lob and drop, seems to think patience, concentration and hard work are unnecessary. Neither man's temperament is suited to clay. Neither man knows how to slide properly. "The points just keep going on and on and it's so frustrating," McEnroe said. "I don't think that the most talented players necessarily win here."
Wrong.
