Hi Ant, you remind me (both visually and in the way you speak) of Rocky Gervais - I wonder if you're fed up hearing that - apologies if you are. A couple of thoughts spring to mind. Though I've never used an R41, my understanding is that it's best when the blade angle to the skin is shallow. You're using it at a steeper angle (blade to skin, not razor handle obviously) than I do any of my razors. You actually say it yourself towards the end of your first pass. Try using it with the handle at more like 70 degrees to your face. Also, you say that you've made the lather a bit wetter than normal, but to me it still appears a bit thin, though I can't see on the video whether it's thin and dry or thin and wet. You're doing well to prevent yourself applying pressure, though - nice short strokes and a relaxed grip of the razor.
