Thoughts on PNL?

[flight2q]

What I found alarming is that volume 1 leaves off saying that it won't so much as discuss how big a raise preflop one could call with a small pocket pair - that's reserved for volume 2 due to lack of space. How can the readers think that volume 2 will go into any real depth unless it's 4 times the size of volume 1?

I can appreciate if you want to spend a lot of pages establishing what vernacular you will use and a structured way of thinking. But just tell me there will be 5 volumes.
