Also I haven't seen anyone point this out yet (maybe because it is not illegal) but regulation A4b says, "The competitor uses their fingers to touch the elevated sensor surfaces of the Stackmat timer."
I don't understand the point of this post. Is the concern that mostly his palm is on the sensor surfaces? Because it's clear from the photos that his fingers (the lower parts of them, away from his fingertips) are indeed touching the sensor surfaces.

Well, I just thought that the regulation meant all parts of his fingers must be touching the sensor surfaces. The regulation does not define how much of the finger needs to be touching the sensor surfaces, which is my main concern. If all you need is just the lower part of your finger that can easily give a 0.1 advantage, since your hand will then be closer to the cube.

But...

His fingers are touching the timer here, the main issue is that his hands slide off the timer meaning that he could touch the cube before the timer actually starts which saves like 0.2 seconds

Instead, we can use this method that Ibrahim Khanani uses instead https://docs.google.com/document/d/1syPge3vcj1oMw7l6qaRPgFdXmUZnkf3U0jNWoBAPkVk/edit

Here, he measures the pure exec time and compares it to the recorded time. In the first solve of the 0.78, the pure exec time (0.76) was apparently longer than the recorded time (0.74) he got. This could be proof that Yiheng did a turn before/after the timer started/stopped.
I would like to point out this sheet as well -> https://docs.google.com/document/d/1SU_Uc5BFEw9X_XNl5-mePkt-QadGFBoRL1S8X5XljO4/edit

This also shows that YiHeng's first solve was framecounted to be 0.76 which is slower than his actual time. Like you said, this is impossible to do without cheating (doing a move before inspection). Also, taking a look at Zayn's 0.92, this framecounted avg is 0.75, meanwhile Yiheng's framecouned avg is 0.777 So this means Zayn's average was technically faster than Yiheng's. 0.78 - 0.777 = 0.003, which means he took on average 0.003 seconds to pick up the cube. This goes to show how impactful sliding can be. My friend from the WRC said that sliding can potentially violate 3 regulations.

It is not entirely accurate to conclude that. Framecounting at 30FPS is inaccurate by +-0.0333... seconds, so if there is a discrepancy smaller than that value, there really isn't much you can infer.

was gonna make a video instead of just talking about it but cba

the issue here is that sliding starts are nigh impossible to regulate for everyone everywhere, or even just for the highest level of solvers
this ties into a larger issue with speedcubing imo which we saw with magic and master magic. We cannot reach a goinmul state in any event before the means by which we measure the event start to give way. we can't fully optimise an event before the stackmats and cameras timing and recording the solves just don't cut it anymore.

the next steps are either that 2x2 gets the axe - like magic or master magic did, or that we move all results to legacy and enforce 4-pad starts. The secret 3rd option is that we just don't care and let it slide

Don't complain that someone does a slide start and it gives them an unfair advantage over you. Just do what they are doing and call it even. Geez. Childish.
I kind of agree with this. If it's impossible to easily enforce this rule, I think the best solution is just to make it explicitly legal. Either that or we change the hardware to prevent this (people have been talking about 4-pad. I don't know what that is but I'm assuming it's an attempt to do this). Otherwise, I think there's too much grey area and that creates a lot of problems with whether people want to record their solves, what kinds of solves get more scrutiny, etc.
It seems like Yiheng's records are not going to be invalidated, which is basically an implicit legalization of sliding starts. Everyone else will have to do it to get competitive times, so it will eventually become the norm unless the WCA takes drastic action (which they don't seem to want to do).

During a track race if someone starts running before the signal for the race to start causing this person to win a race would this be ok? No. This person would be getting an unfair advantage over other racers. Oh right everyone should just start running before the start. This is same for cubing, you should not get a result faster than what you really achieved.
