I have taken (today) new data for my Sea-Dweller 126600 with fully wound 3235 caliber.
Here is the dependence of my timegrapher amplitude readings on lift angle setting:
51° - 272° +/- 2°
53° - 284° +/- 3°
55° - 295° +/- 3°
57° - 305° +/- 3°
Measurement time: 2 min with 120 readings for each data point; vertical lines in the graph below are the precision values (1-sigma value = error bar).
Result: about 5° amplitude increase per 1° higher lift angle.
Measuring at 55° instead of the correct 53° overestimates the amplitudes by about 10°.

Measuring the variation in amplitude based on lift angle changes on your Timegrapher is not very accurate.
Why not just calculate the difference?
