A margin of error does solve the problem. A guy who is 5.01cm offside has much much less of a complaint than a guy who is 00.01cm offside.
 
The reason why there needs to be a fairly significant margin of error is because the VAR lines are trying to apply a very exact science to something that's rather inexact.... for example I highly doubt a football pitch is a perfectly flat rectangle where both sidelines and bylines are EXACTLY parallel. Most pitches will probably have some kind of camber too.
The Z axis too (the vertical line the draw doen from s shoulder or knee) placed on a 2d image is never going to be accurate either.
 
And perhaps the biggest problem is that the passing player could have his foot in contact with the ball dor a few frames, which frame they choose could be the difference between on & off If the recieving player is sprinting.

Never been for the line of sight idea as, as you say, just moves the issue on to another aspect.
 
If the new automated system can be that accurate and quick then that changes the dynamic completely and we are in the realms that the technology can deliver a definitive answer.
 
Until we get to that point though (and let’s be honest we aren’t affording that technology up here and other leagues are probably going to struggle - La Liga found out last night they don’t have goal line technology anymore ffs!) I think the system needs to factor in a degree of tolerance that is relative to the limitations of the technology.  Using technology to figure out what the error range between the frames (and then maybe putting on a +\- 10% safety factor) takes away some of the argument - i.e. if player x is a judged a fraction outside the zone even after an allowance for potential movement has been made then there really isn’t an argument as VAR has given every variable possible within the limitations of what it can do.
 
The instances where it is so close that it is even going to matter are probably minimal, but the implications of getting them wrong can be huge.

The cops would have a collective coronary if that was even suggested 

100% with you however I am not entirely convinced the technology is up to being as accurate as it needs to be to make such tight decisions.
 
Image below was discussing a call from August 2019 but is basically highlighting that VAR uses 50Hz (50 frames per second) and picks the image that they can be certain the ball has been played. In the one they were using Sterling was running at 23.4kph and would have moved up to 13cm between frames so there is a possibility that he could have been onside if the ball was actually played earlier.
 
Easiest solution for me would be to build in a tolerance factor to the really tight calls. Should be pretty easy to get an algorithm to figure out the relative speeds that the players involved were travelling and therefor maximum distances covered between frames - i.e. attacker could have moved 20cm forward and defender 10cm back between the frames, therefore there is a 30cm range where the technology is not accurate enough to definitively say where both players were.
 
Carry out the offside check as normal but if the distance between the two lines is within the range then it is too close to call and goes back to onfield decision (or attackers get the advantage even).
 
The main issue at the moment is that we are pretending VAR for offsides is 100% accurate. For the vast majority of cases it is, however for really tight calls the technology being used can’t be accurate enough to give a definitive answer.

Var needs fucked off

They’re a good side but their defence can be got at if you press them. 

Just read that Onana got 2 yellows, 1 in the shootout, and actually admits he checked the rules with the ref so he knew he could be a dick during the penalties without getting a red or banned for the final.
Surely a nice bringing the game into disrepute charge should be warranted for his deliberate cheating.
Utter disgrace from a shameful club

Displays everything wrong with VAR. Cant make decisions on obvious fouls/handballs but can spot someone a few millimetres offside. Jammy manc cunts

What real advantage did he gain by having half his toenail ahead of the defender. The footballing world was a better place before VAR.

Some people never want to be happy.

Get VAR in the fucking bin

Deserved win in the end. Some of those misses in front of goal though 🤦

I honestly think Silva qualifies for disability payments.

wouldnt be if werent 2 up!

Jesus fuck. We sure his fee wasn’t 35M pesetas

Don't even notice I'm doing it anymore, apologies

You know it would be good if we could get through one game without all our players being labelled cunts etc by our own support

Dessers needs support. Every ball up to him he is fighting 2 or 3 defenders

He was but if they had scored from the corner it would never have been called

Pretty good but that wasn’t him

Madrid have, in recent years, mastered the art of being completely outplayed, surviving stupid amounts of efforts at their goal and winning.
Nobody should be surprised at tonight’s outcome
