Best fit to data (blue line). Reference gradient (red lines):-583ms/day/mrad.
Going will vary with amplitude because sin(θ) ≉ θ

- very strange event, amplitude dropped by 1mrad so clock sped up by 1s/day, corrected itself the next morning. Could this have been a spider spinning its web between the pendulum and the casing? This is a really good event to plot as Going vs Amplitude becvause it obeys the pendulum physics beautifully. [link]
