Same rpm on same prop would require the same torque to drive the prop.
However, our measuring equipment is not the most accurate, and atmospheric density and humidity influences these factors without one being aware of it. So slight changes in measured data cannot always be used for 100% reliablity predictions. Measurements within 5% therefore would be safe to consider as the same. (statistical Zero-option theorem)
Hey.
I made the test within 1,5 hour, no change in the weather, and the test with 12% oil vs. 18 % three times over 3 weeks, because of the rather big difference. If it wasn’t the HP or torque that changed, I don't not what it was, but I'm sure, that I can get the same results any day... Backyard science, you know!
