[Invigilator]

We vary our structure fairly often.

2000 starting with 25/50 first level, up to 10K starting 100/200 first level.

We generally do a freeze-out and I structure the (20 minute) levels based on when we want the tournament to end. If we start at 8 pm and want to be done by 11:30, I estimate the total ships that will be in play and make sure that we get to a point where the BB is 5-10 % of the chips in play around 11:00-11:15

Rebuy's are much harder to estimate, but we will usually start with 2000 in chips and play 25/50 50/100 75/150 for the first hour, end the rebuy period and continue with a doubling structure from 100/200 after that.

as a general rule, I like 20 minute levels, and for my guests to start with around 40-50 BB.
