Absolutely agree. It should be used where the ref/linesman has made a fairly obvious error of judgement and not in a case like this where mm are involved. Take a page out of Rugby League's book and trust the referee's decision i.e. if the ref thinks it's a try and the video ref can't disprove it then it stands and vice versa.
Indeed.
Who even refers calls as tight as that to the Video Ref?
