Almost good, but two points:
- The "Start logging after" timeout should match the flat part in the beginning, otherwise you get some strange effects in the beginning when the RPM stabilizes.
- You don't need the flat part at the end.
- If you have enabled "Enable correction for rolling resistance vs speed from retardation data", then then brake turns off at the end of the curve
- If you do not enable this option, the brake stays on to regulate the end RPM
You can alternatively use the Power sweep for a regular power sweep like this.
