Commentators would really benefit from bringing a sheet of paper into the booth with them. For each game write down simple stuff like whether it was a B&R, or a player made an error, or scratch on break. And the score.
Commentators have a lot on their minds and easily get distracted just by the need to fill air time talking. So they very often forget the score, or over estimate how many B&R's a player is on (they say "he's on a 4 pack" when he actually pushed out twice). If more than 2 commentators are in the booth, these mental errors go up 10x.
Right you are, Jeff. I've suggested the same previously.
At one of the recent events, one commentator said something like, "I think that was the first B&R of the match." The other commentator replied something like, "No, I think there was one earlier." It was actually the 5th one of the match.
A significant percentage of all stats-based statements made by commentators are wrong. The simple use of paper and pencil could prevent a good deal of that. Some commentators do try to take notes but still make a lot of errors. Just too many distractions, I guess.
