Ok that’s a new setting for me. Im referring to the RPM Factor in my post (the engines stroke).
I can’t see it in the manual so again my guess would be the same as the GPS settings and this is the accuracy of the rpm data recording. So if you want to see changes in your rpm to the value of 0.1 seconds then use 10 hertz but if 0.5 is good enough then use 2 hertz. That will save space on your memory (as there is less data) and battery.
When I ran mine for the 24h I used 2 hertz to save space and battery
