shuffle track question

I have read bits and pieces about shuffle tracking, and am open to the idea of incorporating it into my counting arsenal.
Where is the best place to find comprehensive, accurate info about the tactic? I know the basic premises of s.t., but I would like to learn more and be more precise and detailed in my knowledge of it- such as EXACTLY how to adjust the count when different packets of cards are missed, what kind of shuffles are trackable, etc. Shuffle tracking seems to be less of a science to me than traditional card counting- it seems more complex and difficult to be exact. It seems there are more variables than in standard card counting, where you just need to know the true count and the decks remaining. I'd like to hone my shuffle tracking abilities, but am not sure how to best go about this, without risking too much cash. Of course I can start with low limit games and all that, but you'd have to play for a long time to be sure that you are winning by skill, and not fluctuation. I want to be sure I am doing it correctly before risking any real money. Any suggestions on how to best go about this all??? Thanks.

I meant to say, "when different packets of cards are MIXED", not missed. Shame on me for not reviewing my message!

The people that know anything about shuffle tracking usually won't give out any info publically for fear of ruining good situations.

BJ Forum has 3 articles on ST which is a good starting point. Where you play matter most as many places in America may have non-profitable shuffles already. ST is a worthwhile skill compare with doll card counting but people who can do it will not give away real good tracking opportunities easily for fear of educating enamies. You have to treat the shoe like a puzzle and sole yourself.
