Interesting "that lower amplitude contributes to longer power reserve". I can't confirm but would like to see measurement data for this.

Your SD43 came back from RSC Dallas in Dec 2019. Lift angle 55 degrees gave:
DU: 284, +3
CL: 253, 0
CD: 267, +3
CR: 253, +1
DD: 293, +4
Your data yield to X = +2.2 and D = 3, which is very good.

I don't understand why you measured in position CR = 12U and not CU = 3U. Is that right?

For a watch serviced by a RSC in 12/2020 it would be interesting if you could measure for DU the amplitude decrease with time, i.e. from full caliber winding (t = 0) to the end of the power reserve (t = 70-72 h) using 53 degrees lift angle.
