I explained the thicker line rule in this old post and how it was changed and the effect it had. When it 1st came in they used to use those thin lines like the image I just hoyed up but in 2021 it revised. I've mentioned it a few times on here but the majority still don't know it exists or why.
What was wrong with the idea of ‘daylight’ between attacker and last defender? Don’t need a line for that. If there’s a clear gap, you’re off. I agree with this. It means that even small offsides wouldn’t be so bad

It's when 1st contact with the ball of the pass being attempted, not when it leaves the foot. So in theory a player scooping the ball up and over the defence would be earlier than it leaving his foot.
The 2 images shown today of the initial touch and even the frame after still show a clear offside gap and it's more than just a few mm/toenail. It's simply the fact the Coventry player is way over the other side of the pitch that makes the gap look smaller due to the thicker VAR lines being closer near the players. If it was nearside near the linesman it would look quite different and you only have to look at the image in my last post to get an idea of the gap using the linesman for perspective.
Next season the semi-automated offsides will be using a ball that senses 500 times a second for any touch.
If the benefit of doubt was given to the attacking side then how did linesman often get offside calls wrong when the attacker was way onside? I'm also guessing you don't know about the thicker VAR lines that give an advantage to the attacker as explained in the link above in this post?
