There's one point missing from this conversation:

There are a lot of ways an engine can fail. Pulling the prop control back
to improve the glide is only going to work in some of those failure modes.
On an engine with a non-electric prop governor, pulling the prop control
back is only going to help if A) there is oil in the engine and B) the
engine is turning. If the failure is a result of no oil or the engine isn't
turning, pulling the prop control back won't affect the prop.

Which then brings up the topic of what is the drag difference of a stopped
prop in fine (control forward) mode vs. windmilling in course (control
back) mode?

Now discuss. :-)
