Monday evening I was shaving with my Tonsorial Gem (I gotta get more razors) when I noticed kind of an odd thing...

As I was making my ATG run, it appeared almost as if my razor was(for lack of a better phrase) stuttering... it almost looked as if it had gotten stuck on my skin, then skipped up, leaving a few thin lines of lather on my face where it looked like the blade had skipped.

Would this be because of angle, or inadequate lather, or am I just an idiot who needs more practice?
