Pai Gow Tiles Shuffle Tracking

I think I have devised a decent system for shuffle tracking. The problem is that I can't use it at a $25 table because of bankroll issues.

I guess my question is, does anyone think that shuffle tracking can be useful, and I'm assuming that the 12 dot tile would be the tile to track, but correct me if I'm wrong.

To simplify the question (and maybe to get in Ask the Wizard #273, hint hint) knowing that I had one of the 12 dot tiles, am I at an advantage, and how much is the advantage?

As my pai gow calculator shows, the advantage of having the 6-6 tile (teen), with three other random tiles, is 0.213725, when not banking. With the roll of the dice, I don't see how shuffle tracking will help much.

Thanks! I didn't even think to try only putting one tile in the pai gow calculator.
