Thanks for the info.

So we see that most plays are not reversed.

But we also see that on close plays, the kind which are challenged in the first place, there are many times when the refs missed the call. Or the view from various camera angles, a view differing from what the referee saw, reveals a different call to be made.

I don’t doubt that sometimes the refs miss things in the tangle and mass of bodies on the field.
