"t basically seems to be a roulette betting system that, if followed correctly, promises big returns."

Then why is he selling it???

UNLESS the book talks about using physics (to find out where the ball will land, finding crooked dealers (ie **********) or finding a biased wheel, then the method is ****.

Using physics can be done but it is far from easy.

Crooked dealers, well it's cheating and if you get caught (likely) then you are pretty screwed.

You need tons of data to find a biased wheel. They are hard enough to find anyway, and the advantage just isn't worth it.

I'd leave the book alone.
