The 'Test Gestures' dialog can also be used to learn how to perform the movements for best results. You may have to make the gestures a bit different than you normally would for best results.

One mistake I made at first, is not to hold the movements long enough. Once I realised that, things improved quite a bit.
Also try making the intended movement, while keeping the rest of your face muscles as immobile as possible.
Finally, how well your face is lit and how well the camera performes in darker situations obviously has an impact as well ....

For me, the head movements (left/right, up/down) are now 100% reliable (on my Samsung Galaxy S7 FE) and I can keep my eyes on the score while doing them. So I can perfectly use those in stead of my 2 pedal footswitch for turning pages (and more)
Most other gestures are at 85-90 % reliability for the moment, but I will practice a bit more using the 'Test Gestures' dialog and see if I can still improve on that.

So for me, this is a very usefull addition to MobileSheets !

Thanks Mike!
