How many run their tank(s) dry as part of their fuel
management strategy?

I sometimes do. I did it much more years ago than I do now (mostly because
I'm lazy). I especially like that it lets me calibrate my calculations. I
usually run on both sets of tanks (switching at least once) before I run
one dry. It scares me to think that I might switch to a set of tanks with
contaminated fuel. (I sometimes only top off one set of tanks.)
