nwk, welcome! You are correct that using your blade on the same place multiple times can be a huge problem. Might I recommend multiple light passes (with fresh lather each time) vs. a focus on getting smooth on a few passes? I almost visualize that I'm wiping the cream off of my face and taking a few whiskers with it each pass. With whisker reduction on each pass (vs. whisker elimination) and proper lather/face prep you will mind a lot of irritation subsides. Plus you get a very nice shave this way. It is easy for me to dispense this advice since I obsessed over getting BBS on my neck that last 2 shaves and am taking 2-3 days off!
