Ya know...
Neither my eyes, nor my brain is a testing lab.

I can not differentiate within the one second I have to make a judgement call that what I saw and heard were so close together that they need to have a mathematical explination to distinguish which came first, or if they indeed met at the same time.

I have about one second to see it, process it, and call it.
I do not give a $h!t if "mathematically" a tie can or can't happen.
I know that I can't tell the difference when it's THAT close.

And I know that you can't either. If you tell me you can, you're full of $h!t.

When I see a tie, I call the runner safe. That's what the book tells me to do. That's how it's written, and that's how I'll call it.
