Tournament Slope Visualization

Burningyen Compares Tournament Structures at the Major Sites

Reminded me about some work I had done along the same lines about a year ago.

One thing I noticed, in addition to the different blind structures, was the variation in the decay of the field size.

To compare this across sites and tournaments, I graphed the Average Stack Size / Cost Per Round versus number of hands played.

To collect the data I entered the time, level and average stacksize at ten minute increments for a few tournaments.

Cost Per Round is just the sum of the blinds and the antes at that level. I estimated the number of hands to have a linear relationship with the actual time. I think it was about 70 Hands per hour for the online and much less for live.



Notice that by taking into account average stack size, you can compare rebuy tournament slope to freeze-out tournaments. Also notice how most converged around a 10.0 near the end.

This is just something I worked on. Just throwing the results out there to get people thinking of ways of quantifying tournament structure, or how to compare tournaments across type/buyin/structure.

BTW: The yellow line at the bottom left was a local rebuy tournament with a horrible structure. It was Limit first 2 levels and No Limit after that. Hardly any rebuys to speak of. All estimated based on counting tables while I played.
