Two Aspects of Draw: Ben Frisch

[Al Mirpuri]

There is an article called 'Two Aspects Of Draw' by Ben Frisch in the Internet Magazine. He states that it is 44% to improve a pair with a three card draw to two pairs or better. Mike Caro gives a comparable table at www.poker1.com that gives it at being 28.71% to make two pairs or better (I say comparable as Frisch does not specify what his pair is whilst Caro has it as being aces). Who is right? Who is wrong? My experience tells me that Frisch is wrong.

Anyone say differently? Please post.
