Not sure why you've nailed your flag to the mast with this for some reason.
“The frame-rate and resolution of the cameras used in VAR sometimes does not keep pace with the fast movements, meaning that sometimes the player or the ball is blurred.
“So, the viewer has to use their own judgement to extrapolate where the players were at the moment the ball was kicked, which affects whether it is offside or not.
“My research found that the ball was kicked 132 milliseconds earlier than the participants perceived, which doesn’t sound like much, but in a fast-paced game it could be long enough for the players to be in a different location and therefore could potentially change the outcomes of offside.
“This goes to show that whilst VAR is useful to spot obvious errors, it shouldn’t be relied upon completely to make referee decisions.”
New research shows why VAR isn't always accurate enough to judge offside moments.
