I am some what new into straight razor shaving. I just stumbled into an intresting find in seeking out the "perfect shave". My shave is as listed below, I am curious if anyone has tried a similar technique, and with what results?

Normal pre-shave prep (hot towel face wash, pre-shave oil, lather)
1st pass with the grain with a very shallow angle. (my guess 20 degrees)
2nd pass with the grain with a very open angle. (my guess 30-50 degrees depending on the portion of my face.)
3rd pass across the grain with a moderate angle. (my guess 30-40 degrees)

My understanding is that you normally want to stick to shallower angles, yet its also whatever works for you. Anybody else tried this? And with what success?
