All right. For some infos about rake in current OFC online industry, I found this :

- swcpoker (crypto-world) : rake of 2% each hand / caps of 0.90$ , 1.40$ and 1.80$ respectively from small to highstakes
- tonybet (fiat-world) : rake of 1% each hand / cap of 2.50$ for all stakes

Concerning time settings, I would recommend at least 30 sec between each draw and at least 1 min in fantasy land. And a beginner who wants to discover a new game will probably need more. Keep in mind that unlike holdem and omaha, players need a good amount of time to take a decision because they must analyse the settings of their opponents. For example : in a 3-handed game, before last draw, the player in position must take into consideration 31 cards already faced up. It's a lot of information.

Good luck with all of this.
