SSHE Pot Odds question

Hi. Long time lurker, first time poster.

I hadn't really noticed it until recently when rereading SSHE, but when Mr. Miller is talking about pot odds and has the chart on page 30, he says it's for pot odds on fourth street. I always assumed that this chart was good for the flop as well. I obviously didn't read carefully enough to only notice this now. Is there a chart available for the flop pot odds? I see Mr. Miller references "Hold 'em Poker" by Mr. Sklansky, but I don't have that book, yet.
