You should be ok if you are only 20 minutes late. Last tournament you weren't there at all, and as if by magic you managed to finish 10th out of 24. But maybe mostly because a few players didn't realize you were away and somehow managed to lose against you.
This is true! I got distracted in the pub last week, but wouldn't have made it till about half10 this week so decided it wasn't really worth it! Should be around next week though, though Norwich is on tv, so it depends if I try and find a pub in Windsor showing it :S or just listen on the radio
