re: Rory won the Masters with an illegal driver

over a 4 week period? lol. Ok. Does not happen.

You actually are dumb

For every club that becomes non-confirming, it’s literally one golf shot that changes it. It isn’t magic. A club is confirming and then it isn’t. If testing was done after every single shot the club hit in its lifetime, it would pass on one shot, and then the very next shot it would eventually fail.

So your take is the face was massively altered

Where did you see that it was massively altered? Michael Kim said the difference between conforming and not conforming is like half a yard

If a player uses a cat x that’s never failed a test yes its a legal bat

So a rolled and shaved CatX is legal?

Yes or no?

Is pine tar also allowed in baseball as long as your not caught?

Or is it not allowed?

So, no rules? Run what you bring? Formula Libre?

Exactly

Ok, then

So your take is you can do illegal shite as long as you don’t get caught.

Thanks for clarifying.

You just said it doesn’t matter if you cheat, only if you get caught.

So cheating is ok in your book.

If a player brings a shaved and rolled bat into a game knowingly, that’s cheating. If pitchers use pine tar, that’s cheating. Not following rules is cheating. Rory didn’t follow the rules. Full stop.

You are missing the point where Rory's driver passed a test before The Masters.

It was a legal and approved club until this week.

It wasnt an untested club. Every club gets tested before it is allowed to be used in competition. The Taylormade Qi10 is no different. But a new Taylormade Qi10 can have a different CT rating than a used one just like a new metal baseball bat has a different springyness than that has been used to hit a few hundred baseballs


Driver testing explained

PGA Championship 2025:
The news of Rory McIlroy’s driver being ruled nonconforming for exceeding the spring-like effect prior to the start of this week’s PGA Championship has spread like wildfire since first being reported Friday afternoon. So have the questions.
So Rory was using a hot driver, basically cheating, right?
No. This is not a corked-bat situation. While we don’t know all the ins and outs of McIlroy’s specific test with his TaylorMade Qi10 driver because under the process for testing drivers for CT (characteristic time) that is employed at PGA Tour events and major championships, test results are held in confidence, aside from pulling the driver from competition.

PGA Championship 2025: Rory McIlroy's driver deemed non-conforming by USGA ahead
The CT test is a sophisticated but quick field test to determine if a driver’s face is too springy. It uses a scale of microseconds to determine face flexibility where the legal limit is 239 with an 18 microsecond tolerance to make the overall drop-dead limit of 257 microseconds. This is basically like the idea of having a speed limit of 65, but knowing that you’re only getting pulled over if you’re running at 72. However, unlike the speed limit example, the difference between 239 and 257 is simply the tolerance of the measurement device. The difference in performance between something a little under the limit and something a little over the limit would likely be the difference in two drives measured in feet, not yards
