The Silverthorne Blackjack Strategy

I'm just a beginner, having learned basic strategy and used it to pretty much break even at the casinos here in Vancouver, I may not be winning much ($60 total playing) but at least I get to play for a few hours and not pay for it. I came across this site, http://www.casinogamblersbookcase.com/blackjack.htm while looking for more info in the KO system, and was just curious if anyone has tried it or if is worth getting or is it bunk.

Thanks for any info.
