There is a massive difference between noticing a lack of smoothness/brief pause in the GCD rolling correctly than trying to time a 0.4 second difference by eye. There's a reason I brought up the example of how some people can and can't tell the difference between 30FPS and 60FPS. You can notice the difference, but you can't time exactly how many frames are actually displayed per second by eye.
You know exactly what website I'm talking about.
Again though, you deflect from criticism to any point you can dismiss. There is a 100% certain way to prove it and you ignore it. I figured you'd want the ability to finally prove to everyone you're right in terms we can't deny?
It's really tiring, honestly, to debate this issue with you for you to fall back on "LOOK, I MADE A VIDEO IT PROVES I'M RIGHT" when we have ways that can identify, to the exact millisecond, when every single ability fires as determined by the game.
