Hi Chester,
I have had similar results with the Jeti Spin 75. In my case, the voltage and RPM figures were fairly accurate ..... but .... the amp readings were WAY high. In my case, I was getting motor cuts (slow down) due to over amps...... that just should not have happened ! I believe the fine tuning ability with motor timing and acceleration delay, and the brake options (via the Spin Box) are very useful ..... but the feedback data is highly suspect. Personally, I'll go with my Asto Flight 101 Super Whatt Meter data for amps and volts.
