Bluetooth LE or Wi-Fi?
In BLE mode the Handy takes actions one by one and therefore producing a microstutter before each point. Over Wi-Fi it caches all actions beforehand and is therefore more smoother.

Fast actions, one that exceeeds 380unit/s, should be kept untouched imo, as the sudden acceleration feels rather abrupt and unnatural.
Simple script also has better compatibility, and will thus play out better on older toys such as the Launch and A10 Piston.
It’s worth adding middle points purposefully to represent significant speed changes in the video. Don’t select all actions and perform the function just for the sake of “smoothing” out the strokes, as it may not.
The only device that is completely unaffected by this is the OSRs. And there’s no need to do this for them because MultiFunPlayer takes care of overall interpolation.
