The accuracy of the technology is really not the issue here and we're at risk of throwing the baby out with the bath water. This offside tech is undeniably very reliable and accurate, there is no human involvement in calculating the offsides. Huge improvement on "the lines".
The issue is that it measures offside with such accuracy that it is nearly impossible for a person to know themselves if they are offending.
It's an easy fix for me, it just needs an "umpire's call" zone that goes with the on-field decision. Say if the player is less than one foot offside.
