I think John Deakin covered this topic in one of his columns. He explained
why most of the POHs are worded the way they are, even when it doesn't
make
sense. For example, have a look at this article (I think this is the right
one - I can't find the index to his articles on the AVWeb site any
longer):

My impression of the point he tried to make was that the manufacturers
believe LOP operations is hard to get right unless you really know what
you're doing (and have the proper measuring equipment, i.e.: EGT) and that
ROP operations is "safer" from a legal standpoint.

... but it's been a while since I've read his articles on the topic, so
I could be off here.

Read #8, 15, 16 and particularly #18. Those are the basis of the Advanced
Pilot Seminars http://www.advancedpilot.com/index.html (Well worth a couple
thousand $$ to protect a $25-30K engine...not to mention your butt).

If applicable, read the Turbo's series, #31-36, and #59, 63,64 as well.
