Case 10 — 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-21954/10: address this question within its stated limits.
