My 3235 was also accurate towards the end of its power reserve dial up but my TimeG showed that other positions would not have given me anywhere near the same result.

The watch just sat in the timegrapher through the entire 71 hours. In between readings it was dial up. When I'd take a round of readings I would start with the current position (dial up), then switch to crown down, let it settle for 2 mins, take the reading, then put it back in dial up and walk away. So the majority of the time was spent in dial up.
But this is where tracking multiple metrics is key in my mind. Saying it was +/0 at 68 hours basically makes it sound like things were running perfectly at that point. They were not. At this moment, the dial up performance was -17 s/d and amplitude was so low the machine was not reading it. The crown down performance was so bad it couldn't get a rate or timekeeping reading (at 66 hours, the last time crown down produced a rate, it was doing -37 s/d).
The bottom line is, things were deteriorating rapidly, but only near the end, so it didn't have enough time to "pull down" the overall time results too far.
For what it's worth, hour 60 is around the last time I was able to get full readings for both positions. At this time the horizontal amplitude was 173 and the vertical was 124. Timekeeping was -4 s/d and -9 s/d, respectively. So still not terrible timekeeping even with ridiculous amplitudes.
