I've learned an awful amount from following this thread. Thanks to all involved. I'll be honest. I've got a Maths & Modelling background. My style is basically "forensic". I was/am happy with the Lino shoving the flag up if they think it's offside. But, I also recognise that Video Technology can help. Because I trust the Mathematicians who have designed the Hawkeye system. And, I'm comfortable they haven't deliberately stuck a bias in the system. I was/am also happy to let Hawkeye rule on offsides. I get both sides of the argument. I get it inflames passions. I get it results in people telling me to get fucked on this forum. But, what am I supposed to fucking do, lie? I'm OK with Hawkeye for offsides. I don't think those who prefer Lino Flag are idiots, or horseshitters. And, I have no desire to see them get fucked.
So, forensically, is anyone prepared to explain why & how the lines drawn on a single frame are inaccurate? I know the choice of frame is vitally important. Put that to one side. I know the ball & player will be in a different position if you take the earlier frame, or the later frame. I know you might not like "the armpit rule". I fucking know all that. I know you're the World's best celebrator & limbs an' all that. One frame. Multi camera angles to calibrate the 3D space. Drop a virtual plumb line from the attacker. Drop a virtual plumb line from the defender. Draw the virtual lines. A > B offside.
