I think you win.
I got rear flats on the side of the tube on one bike at weird intervals. One day, I got three such flats in eight miles. Really weird. Then I would ride the bike for months with no flats. Then I'd get another such flat. I finally discovered that one of my brake pads was a little too high and rubbed against the tire. The rubbing created heat. Eventually, I wore out the sidewall. The reason the intervals between flats was so uneven is that I rarely use the rear brake on any bike I ride.
