You described my problem pretty well. However, flapping while turning rarely happens so far, luckily. It would make the whole thing a bit mor complex.
Using the draw function I noticed that the drawn lines are somewhat off/odd.
Even though I disabled the tracking by world location the controllers seem to be constantly traveling forwards and the line is drwan around 50cm to 75cm infropnt of the actual controller position while the controllers are beeing tracked just fine.
The gesture I’m using is, for the sake of consistency in recognition, a simple downward pull on both controllers simultaneously. Before I was using a whole flap cycle which the testers failed to reproduce (even though they recorded their own cycles).
The main issue is resolved I think, just the draw is off somehow.
