Don't understand why you have two axis titles, what is plotted vs. time: Deviation (s) or Average rate (s/d)?
What is your overall conclusion?

Hi Saxo. Thanks, man. I'm plotting average rate, forgot to change the Y axis title.
My answers to your questions:
1. Yes, the watch was at rest in dial up position. I probably wound it up because it was getting close to the 70h PR. I can't remember 100%.
2. Nothing happened in the first 200h. Same dial up position at rest. Agreed, erratic at first but very consistent after that (next 1200h).
3. I have no explanation for the increase / decrease. Same methodology, the watch didn't move.
4. Same test, although only during 52h (dial up at rest, one single full wind at the start).
My conclusion: my SD43 seems to have gone from spec (+2/-2 s/d) to out of spec (-5 s/d) in a 5 years timeframe. Still acceptable to me. Warranty expires next week, I won't be taking it to the RSC unless things get significantly worse. To me it's just not worth it. I love the watch all the same.
