This.These offside calls aren't really a VAR issue though. Offsides will always be a matter of fact decision and under the current laws and with the current technology (people will claim it's not 100% accurate but it's far more accurate than a lino's eyesight), if you're leaning 1mm offside then it's offside.
The issues we're having with these offside calls isn't VAR but the laws in their current format. Imo they need to scrap the 'any part of the body that can play the ball' bit and just use foot positions.
The offside thing is a problem with using tech to steadfastly implement a rule that's crap, rather than the tech being substandard.
