Determining the maximum endurance speed

Hello!
Just found your forums and I'm very impressed by tons of information you have here!

My question is: How to determine the best endurance speed using an experimental method?

For ex. I can find the maximum range speed by changing the power from cruise setting by 100 RPM and see what drop in speed I'll get. For ex, cruise is 2300 RPM, I set 2200 rpm and get a 5 kts speed drop, then I go to 2100 and so on. At 1900 RPM I get the drop more than 5 kts (approx 10). So I go back to 2000 RPM and lean the mixture. This is the best range speed.

These settings were used on Cessna 172, but I guess it works on all small airplanes

So, how to find the maximum endurance speed the same way?



Thank you very much!

Maxim
