I've said this for a long time mate, the TV technology doesn't support the accuracy that they are deploying it to and there is an awful lot of subjectivity in when to choose as reference points. Smoke and mirrors, smoke and mirrors
There's a world of difference between technology and science. The two are being conflated here to lend some sort of infallibility to VAR.
There is no way this would stand up to rigorous scientific testing standards. There is no basis for this measurement because there aren't two definite points that are being measured: the point where the foot strikes the ball to put the pass into motion and the point where the player meant to receive it is standing when that happens.
It's arbitrary and therefore BS from a scientific perspective.
The whole of VAR is fundamentally subjective: from the way the laws on what's to be seen as infringement change from month to month, to what constitutes contact, to how offsides are measured.
It's a BS system that's been deployed by the industry to determine game outcomes and trophy winners.
It's as corrupt as sport gets. If we gave all players EPO and let them play football it'd be less corrupt than VAR.
