I try not to shave if I am in a rush. There is not much relaxation in rushing anything. If a casually stroll into the bathroom and strop my razor do my prep and shave, clean up a little and do my post shave strop it is usually around 20 minutes, and 2.5 passes. That is 20 minutes of relaxing and satisfying prep and shave time, if I only have ten minutes, I don't have time to shave.
