I posting in anticipation of questions from my players at FNM this week (and to sate my own curiousity): is there are prescribed algorithm for determining # of rounds at a GP? Since it looks like GP Las Vegas is going to be off the charts, I wonder if that formula breaks down at all, especially with # of byes.

GP have a fixed number of rounds now. 9 rounds on Day 1 and 6 rounds on Day 2.

“Grand Prix will have a maximum of fifteen rounds (nine rounds on Day One, six rounds on Day Two), followed by a Top 8 playoff. For individual Grand Prix with 1,200 or more competitors, Pro Tour invitations will be awarded to all players with at least 39 points at the end of the tournament who do not make the Top 8.”

GPLV will be exactly 15 rounds. That is the maximum number of rounds, due
to the recent change in GP policy from Wotc.
