Lol @ "most probably deliberately," yeah, because I'm Trump and a forum argument is so important for me that I'm desperately trying to swing the narrative. Look, I don't have a problem with you but if your perspective is too narrow to understand a simple point, that's not my problem. The reason I posted the above is to highlight how players (in this case Murray) highlight the importance of other factors when it comes to how quick a surface plays (conditions, balls used, etc...), as opposed to providing a scientific study that is supposed to be the end-all be-all. So again, you do understand that balls and conditions also play a determining factor in court speed right? Or is your bible of an article the only thing we need to look at and not more?
Also, lol @ "this explains why Roger found it a little easier at the AO," when he won Wimbledon far more easy and cruised through the tournament without breaking as sweat.
Now again, please explain to me how is it that people whose games you'd expect to do well on fast surfaces like grass are doing far better on grass than they are at the AO, and how Nadal continues to struggle so much at Wimbledon if the surface plays slower. I'm not saying this is irrefutable evidence or anything, but if you don't think everything we see from the brand of tennis being played, to the shorter rallies on grass compared to the AO (particularly the first week), the higher ace count, to the results themselves indicate that grass might still play quicker than the AO then you're really bizarrely infatuated with your article.
Also, it's very convenient that you (most probably deliberately) ignored the following part:
"Also important to note that grass has always been an erratic surface to measure, because there's quite a difference in court speeds depending on cover, age and length of grass, wear and tear, etc... So for example, if the surface speed is measured towards the tail=end of the second week of Wimbledon, it's not that surprising that it comes off as Medium to fast. But if it's measured early in the first week, it'll likely be much faster. And we don't know when the surface speed has been measured at all, but I'm sure
@GameSetAndMath and his otherworldly fact-checking, researching ability, and wealth of tennis knowledge can help us out."
And also, just for curiosity's sake, please explain why Roger being less dominant at Wimbledon than Rafa is at the FO is due to the nature of the surface if the surface doesn't play that quick anymore and is even slower than the AO. I'm just offering two different arguments that you've provided and wanted to make sense of them.
