Here the 33ms we are talking about is the interval (horizontal distance between two points). If two points are this close, they may be omitted when played under BLE mode.
(Note this is not an accurate threshold, just the author speaking from experience. As mentioned above by Krich this is susceptible to many variables.)
The “33 unit/s” we talked about in the other topic is the minimum stroke speed. Handy can’t go slower than that without stopping due to hardware limitation. This has nothing to do with Bluetooth, it also affects wi-fi playback.
How spaced out a point can be placed depends on the framerate of your video. For a 30fps video it’s around 33ms, but with higher framrate you can easily place two points closer to each other. You can use the “FPS Override” feature to force this and ignore the video’s FPS.
In conclusion keep speed above 33 unit/s and interval above 60 ms if you want your script to be highly compatible with the Handy under any modes.
Or just do nothing - None of these limitation presents on the OSR. Might as well see that as a standard and force some changes on the Handy’s part (they promised a firmware update to address these issues last year but it didn’t come).
