I see you've just taken the rake structure from Seals, which has some problems for HU and shorthanded games.

HU rake cap is way too high. Needs to be one chip at most.

Also, HU and shorthanded rake at regular tables need smaller caps. HU should always be 1 chip or .5 chips, no matter where it's played. 3-handed should always be 1 or 2 chips. Those of us playing short at regular tables are starting games for you and should be paying the least rake. (Seals also gives 50% rakeback to table starters.)
