Pete, that is good. But not all POH's are created equal.
We (APS) know and actually highlight in class, several POH's that are, lets call it sub-optimal in terms of reliable information. One that springs to mind is inflight restarts. Don't ask me which one off the top of my head, but lets just say the book describes a process that makes it worse not better.
So the idea is understand the science, then you can critically think through the POH and determine if the one you are reading is a gem POH, or a POS.
Cheers
