I have used the system included in the book in many freerolls,including the WPO warmup which im now qualified for round two, with the following mods: check big blind if not all in and go allin if nuts fold otherwise, and unless AA or KK never allin twice in a row(too likely to get called) I dont it in real money and only do slighty better,i estimate that with about 6-8 more mods the system would work as good as or better than my reg play.
