Slight stutter when sensor mode turns off

Hey guys, noob here ;)

Just installed a flipsky 75100 on my scooter and there's a slight motor stutter, like a single short 'tah' when it transitions to sensoreless mode.

It is set to go sensoreless at 2000 erpm so it happens really fast at very low speeds but if I increase it to say 6000 erpm then it will do that same stutter only a bit later.
If I change it to 30,000 erpm then it never does it as it stays in sensored mode the whole time.

My question is, why do I need to let it turn off the sensors?
and why does it happen instead of transitioning smoothly?

Also, one more question I couldn't find an answer to...
In the phone app, the throttle calibration wizard, it says to go full throttle and then leave it in the middle.
Didn't quite understand that, should I click save while holding half throttle? seems a bit weird.

They chose to not publish the firmware source code, which is illegal BTW. So nobody will be able to really understand this unit and help out. I guess you need to get back to Flipsky for help.

The wizard works in a way that you have to give full inputs and then center the stick (in case it is a stick with positive and negative input, forward and reverse) if it is just a throttle, you need to bring it to full throttle and back. These inputs are then mapped to 100% and 0% throttle.

Hmm I don't think it's any different than any other vesc software so I believe my issue can be fixed with just common vesc knowledge.

About the throttle, so I give it full, then release and click save after release? not saving during throttle or something right?

Yes, you need to apply that and then finish the wizard.
