It won't top at 2k, mostly because I need the tournament to end at a reasonable time. We did 1500 for the tournament last league, and I think everyone had ample time to finish their games, so I'm leaning towards 1500 as being the top end.
We still had a lot of games done at 1000 points in the first month, it's always the 3rd month that had a drop in games mostly due to time constraints.
I think our options can be:
500/1000/1500
750/1125/1500
1000/1250/1500
