I couldn't imagine someone who only got 1-2 flats in a decades would have any advice that would be worthwhile to my riding experience.

Now your friction is far lower than it would be dry and the bead can scoot right off.
When I read the OP I was wondering about the soap he used. Not all soaps are the same and I could see this contributing to additional slip at the bead seat. I know the tubeless seating fluids are often specificly formulated to remain lubricious when wet and once dry have a matte feeling texture.
