Some years ago ABC WideWorld of Flying did a demonstration with a C-182.
He demonstrated both glide ratios and minimum sink with engine at idle, engine idle with prop in course and fine positions and with the prop stopped.
Results were very impressive. If I'm remembering correctly, delta between engine at idle, prop at fine pitch and prop stopped, the glide improved something like 26%.
I'm pretty sure I still have the tape. I could dig it out and run it again.
