I do still wonder if magnetism plays a role: small parts, with tight fit tolerances, become magnetized, friction results, but it goes unnoticed until damage is done because the springs are antimagnetic.

I'm still not sold on this magnetism theory. Brass can't be magnetized. And there's no reason to believe that 32xx owners are more likely the be in intense magnetic fields than 31xx owners.
Low amplitude is the cause of the poor timekeeping, but the excessive friction seems to be the cause of the low amplitude. For those of us who have been able to measure declines in amplitude, the amplitude itself drops off faster than the timekeeping. For example... my Sub is 18 months old. I've worn it probably a total of 30 days in that time. Amplitude started low when new, but has gotten worse since (even at full wind). Yet timekeeping is still very good if the PR is topped off. I don't use winders. So I take the watch out of the box, fully wind and set it and wear it that day. By the next morning the amplitude is well below 200 degrees (out of spec) but I'm still within a second on the time. So for now, I'll just leave it be. It's clearly not 100%, but it's working for my purposes and I feel I have the best chance of a "real fix" the longer I wait into the 5 year period to send it in.

We have long ago crucified this poll as meaningless and unscientific :) That said, it has been uncanny how the % of problem vs no-problem has stayed within a very small range all the way back to the first 50 votes up to the near 1000 we are at now. Users can only vote once. So for there to be 280 users on one forum which are reporting some kind of issue, I don't see how that can be written off as a nothingburger.
And of course the standard caveat applies. There are like 200 million seconds in a day so we shouldn't worry about being 1ms off the atomic clock.
