I understand the perspective. I've gleaned from your other posts that you don't care about a couple of minutes per ride, and your type of work does not prioritize punctuality to the degree that the rare tardiness from a flat is a problem. But then you wrote that you're starved for time to a degree which has me curious. You have enough data now for a real rough estimate of the probability distribution function of flats on your route. Have you calculated the (time) expected value per ride of walking the bike as opposed to changing the tube?

My job (and commute distance) is similar in that it wouldn't objectively matter if I had a flat and walked in. But such is my psyche that I'm not going to be late unscheduled, ever, so I carry the tools. I'll also save the couple of minutes per ride, probabilistically speaking, and a couple more by riding harder. It adds up.
