I believe by "it" the original poster was talking about David Wu's
bag of tricks for penalty methods, not the penalty technique in general.

See http://www.pseudointeractive.com/games/penaltymethods.ppt

Unfortunately, I was not able to attend this talk, so the slides are
my only source of information on David Wu's techniques for penalty methods.
He seems to swear by them. I, too, am interested in hearing from people who
have tried David Wu's suggestions, since most penalty sims suffer from
the well-known problems.
