Best fit to data (blue line). Reference gradient (red lines):-605ms/day/deg C.
this is for an uncompensated steel pendulum -605ms/day/C (we hope to acheive within 10ms/day/C with compensation)

- TC works staff were checking out clearance in the pendulum case - they must have touched the pendulum

- ADJUST: -500 ms/day to 28700 Now that the pendulum is swinging nicely we can see that the temperature compensation is not ideal - sticking somewhere?

- ADJUST: +500 ms/day to 29200 maybe the new suspension is settling in. No matter how tight the screws are the spring will ratchet down against friction.
