Sklansky and the System

[kamelion44]

I just finished up a big multi-table No Limit Hold 'Em tournament. What are your opinions of the Sklansky System that is put forth in Tournament Poker for Advanced Players? I'm referring to the all-in or fold system. I used the revised system for much of the tournament, and I finished 6th, my highest ever for that large a tournament. Does Skylansky himself still stand by this system? Are there further writings and refinements of it? Thanks.
