I expected the Amplitude to decrease as power ran out but toward the end it increased quite noticeably.
Saxo3 has also nioticed my results and commented on them.
Now I am scratching my head (I hope I dont get any splinters).
Why woukd this have happened ? .. i cant make sense of it at all.
Any clues anybody ???

Hi Charles,
Your first ever taken timegrapher data must be viewed with great caution.
The measurements were not done for one single position but for all 6 movement positions.
This becomes especially critical towards the end of the caliber power reserve.
Since the caliber is moved on the timegrapher, position stabilisation becomes very critical especially for amplitudes below 160 degrees.
Looking at your Table 2, I conclude that the last meaningful data point was taken after 62 hours. Until this time the data points fit into the general behaviour of 3235 movements, i.e. the normal amplitude decrease with time.
The next set of measurements was taken only 7 hours later, i.e. by far too late. Your timegrapher indicated the following numbers:
After 69 hours
Horizontal positions: -13 to -45 s/d and 285 to 268 degrees
Vertical positions: -41 to -166 s/d with 203 to 233 degrees
After 72 hours
Horizontal positions: -30 to -123 s/d with 189 to 220 degrees
Vertical positions: -163 to -467 s/d with 126 to 309 degrees
Based on my experience, these data points are unexplainable, unrepeatable, and (sorry) total crap.
Therefore, I suggested that you repeat this measurement in fixed DU position, take much more data points, not only towards the end of the PR.
Good luck! Cheers
