I don’t understand why the chart is made for 2500 rpm. I usually decend at 2100 rpm. Do you know what to do about that?

Sorry for the late reply. That is a great question. I also use 2100 rpm or less for descent. I couldn't find a good answer anywhere but I assume it is only used for fuel calculations on this chart so they use 2500 as a more conservative number for fuel. That's my best guess.
