a new razz pupil

[olmaters]

so ive decided its razz im going to focus on 100%. being new to any kind of stud game i was wondering what math about the game is important. id like to commit to memory as much about the game as i can. so what probabilites odds and the like should i know. ive looked at the mike caro odds section in the back of SS as well as the last section of the potlimit no limit book by ciafone/reuben and their odds tables are very different i dont see how they can be coming up with these different numbers. thanks
