Case 35 — Timegrapher reading context: what do rate, amplitude and beat error actually tell me?
I ran a watch on a basic timegrapher and got +6 s/d, 245 degrees amplitude and 0.8 ms beat error, dial up, about an hour after winding. Is this good, bad or normal? I don't want to send it for service on a single reading.
Exercise RWI-19445/35: address this question within its stated limits.
