VAR precision and the error-budget problem

6:37the ruling is extremely precise, okay? They're saying, "Oh, the arm is over the line, but the body is not," as you're saying, right?

It's like [clears throat] if his body was a few inches this way or that way, it would have been offside or onside. Okay. That is where I started calling BS. Okay?

7:18is that the plus or minus, like in that judgment, is is within a few inches. >> Yeah. >> Okay? How are you getting that precision?
