Duffman,
It was great meeting you last night and it was really fun.
The thing I was talking about before we all had to skeetdadle was what we did at IWPS this year in Berkeley. Basically, myself and Mike Henry took turns talking to the judges before hand explaining to them
a) that their job for the show was important
b) that they are right despite what the audience says
c) that score creep does exist (explaining what it is to them)
d) and that if they feel that a poem in the last round is less strong than something in the first round they should score it accordingly
e) 0.0 is the worst score ever, the poet should be asked never read that poem again and that 10.0 is a life changing experience, spontaneous orgasms throughout the room, etc.
I think a combination of the two of us saying it to them and taking the time to explain it to them really helped. That being said, putting too much pressure on the judges at a regular slam may disinterest people from coming back so I would utilize the tactic that we used at IWPS judiciously. Save it maybe for a finals night or for a big regional tournament.
Other ideas for combating score creep include having the judges keep track of all the scores through out the evening, and...
