When I first started with an SR a few months ago I had the same problem. Skin stretching made it better, but before that I ended up trying different angles and different light pressure with about 1" long strokes. I started back by my ear with about a 30 degree angle, then moved forward at a little less angle, and forward again with a little less angle. I then went to the other side of my face and did the same thing, but increasing the angle from 30. I then ran my hand over the areas to compare how well each angle did and chose what appeared to be the optimal angle. There was still plenty of hair left so I went across the areas again with my new optimal angle and varied the pressures. I wound up with razor burn and a few small cuts, but I also had my beginners angle and pressure. From there it was just small tweaks.
