The rate is fantastic but I am not sure about the amplitude [nt]

depends on angle....flat is 350....think 320 is regarded as ok...but happy to stand corrected...also not sure what lift angle is and guessed 52 [nt]

Impressive outcome, but the amplitude isn't a tad too high? [nt]

Hopefully someone can give us some insight [nt]

270 degrees is top, as far as I know, for a balance spring made from an alloy

But maybe for a silicon balance spring this amplitude is fine?

I provided the hodinkee link [nt]
