What is "small stakes hold'em" in SSH?

I've just finished SSH for the second time, and low limit hold'em strategy finally made sense to me. But now I wonder how far can I get with the guidelines and strategies in SSH and when should I put my teeth in HPFAP? I realize there are no such thing as a sharp line between low and mid limit poker, but how high on average would you guys say that the gaming conditions remind of those explained in SSH? I'm talking about online poker.

I recall something is said about this in the book, but I'm asking because the situation could have changed somewhat since the book was published (it always does, and the book itself can of course have changed the small stakes games)
