The short answer to your question is; the Mini-500 cruses at 70% power
available at it's operational RPM, which is at 90% of it's total duty
cycle.


Hummm, you or someone else is not being truthful, about the percent power
and RPM's the engine had to run at.


I can't speak for what others have told you, nor their honesty about the
topic or how gullible you are to believe them.

However, me as the designer and manufacturer of the aircraft is stating
to you the numbers I given here are correct. I don't care if you believe
me, no skin off my teeth.


Also, the factory being eager to sell engines for the 500 is not quite what
I heard.


I can't answer to what you heard, nor can I help what other people tell
you, and I can't help what you choose to believe, nor do I care.

I can only warrant that I said the above, and I stand behind what I said.
