I used to have a much thicker beard that grew ferociously and required daily shaving. Unfortunately, a medical condition has led to a much softer, much more slowly growing beard. Couple that with my mandatory round beard (by order of my wife and daughter) along with a three-pass DFS+ shave and there just isn't much to shave every day. For example, I had a terrific shave around 24 hours ago and there is just now barely any stubble pushing through my cheeks.
I had this thought a few days ago, do a less thorough job of shaving so I have to shave more often. I am going to start this the next time I need a shave. I think one WTG and one or two XTG passes should work.As my technique developed, I was doing three passes daily; WTG, XTG and ATG. This ended up giving me a too-good BBS result that meant I only had something to shave every 48 hours (10½ passes per week). I then dropped the routine down to two passes daily; WTG and XTG. This gave me a DFS result and allowed me to again shave daily (14 passes per week).
After further experimentation, I found that I could do three passes; WTG and 2 x XTG, and get a DFS+ and still have something to shave in 24 hours. This brought me back to 21 passes per week.
I still do an ATG pass with every shave but that is limited to my upper lip. Some call it a "fool's pass". I do this ensure that the blade's edge is up to scratch.
