I saw this too. First time I've seen this feature. I hope they keep doing it.
I saw three instances and the 235 carry for 325 total distance certainly got my attention. The three drives I saw had carries of 235, 245, and 271 (Schwartzel, I think) and total distances somewhere around 325, 285 (ended in a bunker) and 315 respectively. I saw one other where someone hit a tree - the carry was like 255 and the total was 255 which sounded reasonable. The carry yardage stopped when the ball hit the ground. The roll out distances were huge (except when they hit a bunker or the rough). The lower trajectory shots had more roll out. The higher ones less. Seems reasonable to me.
In a 2009 study Swingman Golf reported that on the PGA Tour "The average shot hit with a driver carried 260 yards and traveled a total of 287.3 yards, including the roll." The results yesterday at Riviera are not so unusual given these averages. Riviera was reportedly playing very firm and fast yesterday, so the roll outs were large.
Makes me feel better about my 210 - 220 yard carries. Now if only I played on courses where my average roll out was 27 yards that'd be nice.
I guess maybe it's not ALL about the ball.
