Normally I take 40 min but now I'm getting 20 min shaves. The trick I used was to do 2 WTG passes before moving to 1 XTG, and 1 ATG passes. I got a styptic pencil (boy I wish I had this before) and just light touches with it stops the small nicks and even some larger ones. After using the pencil I could finish up with Witch Hazel and ASB. Also some of my techniques (blowing up cheeks) are starting to payoff in that I don't have to do as much buffing at the end.
Also by speeding up my strokes and making them lighter, and shorter the extra WTG pass didn't add time and reduced buffing time. My next goal is to get a DFS in 10 mins with no major nicks and cuts.
