It's fast but you can give yourself enough time to stop and think about what your saying. Especially something as simple as Gerad Adams, or Scott Matzka.
If preperation is taken then I would assume they watch warm up thoroughly to get the feel of the size and facials of each player to make it easier to call when the numbers are out of view? Or to have a list of pictures (if available on websites) in order to help? Always helps to be thorough!.
I think the main point is we could all understand if it was one or two mistakes, but constant mistakes it just doesnt make sense when they have had so much practise.
