Hi Jer, I am prone to stick with what I was taught, too. But . . . the lowest string on the treble bridge has the greatest seasonal pitch alteration. And . . . . . . on many pianos the distance from bridge pin to rim is equal to or very close to the same measurement on the top string of the bass bridge. This one small observation has for decades bothered me because it shoots a hole in my reasoning. So this thread has interested me and I am open to all other considerations.
