I fully share and confirm what you say with many timegrapher measurements of my 3235 and 3285 movements, as well as the analysis (and graphs) of data provided by others in this thread.
It also confirms what I posted before:
I have NOT even seen 1 (one) contribution on TRF where a member has shown (with data) that his 32xx watch keeps (or kept) high movement amplitudes (after full winding) together with good timekeeping over a period of several (4-5) years, i.e., starting from the date of purchase and without any RSC repair or regulation of the 32xx movement.
Bas, I found a parameter to distinguish between good and bad 32xx movements, based on their different isochronism. It is quite a new insight for me, which I did not post or see anywhere else.
What's your experience with the isochronism of the 32xx?

Funny that you say that about isochronism. Those who run at very low amplitude and give you the most trouble during a service are running with very high and inconsistent Delta values as well, thus poor isochronism.
The ones that get great amplitude after a service generally lose very little degrees in amplitude after 24hrs, and they have tight values as Delta. When running well these 32×× movements are capable of incredible accuracy/timekeeping.
