I tend to agree with not over thinking it. When I was breaking spokes I tried different pressures thinking it was going to help. I fiddled with PSI differences of only a few. I went out one morning and the tyre was so mushy I could feel it roll the tube on corners. I got advice from all sorts of places, and it was all greatly accepted, but when I finally gave up and accepted my issues was with the light weight wheel the bike came with and got a new wheel, tyre pressures really did become something I stopped worrying about. I do have a figure I inflate to, and I finger check the tyres every few days but I don't check before and after every ride that I have a set PSI in each tyre.
