More proof that VAR for offside is flawed as discussed on Bluemoon last week

Cameras used by VAR run at 50 frames per second. One picture taken every 0.02 seconds. To the human eye, it looks like a moving image.
For offsides, VAR has to choose the frame which shows the ball has categorically been touched. If Frame A shows the boot an inch away from the ball, then VAR has to take the next one in which the ball has definitely been played.
In reality, though, the first point of contact will be somewhere between. And as The Mail on Sunday has calculated, for decisions as tight as Sterling’s, a player can move quickly enough to move from onside to offside. And that’s crucial. It means there is a margin of error. And that margin varies depending how fast attackers and defenders are running.
