did game 6 start ? Before 11 AM CST on Saturday ? If it was before that then you've got a case. if it was after that then I misunderstood you and wouldn't advocate a replay. The schedule clearly said that aways were due 11 AM CST on 12/6. If the games were played after that and you didn't have aways in then I think you very unfortunately goofed.
My interpretation of the rule is that the day between games 5 & 6 isn't necessarily 24 hours. It means, to me at least, that game 5 is due on 12/5. If played by the manager it's 11 AM 12/5. If the robot plays it then it's sometime after that but still 12/5. Game 6 aways are due at 11 AM CST 12/6 and the games are then turned on, not always at 11 on the dot :0). If you thought that the clock for the one day gap between 5 & 6 didn't start running until the completion of game 5 then you were mistaken.
Sorry Patrick, it does suck. Hang in there.
