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)

- ADJUST: +100ms/day to 31150, thanks again Hilary. I have a far-fetched idea that going is proportional to long-term rate-of-change of temperature at -200ms/day per degC/day. This minor adjustment should help test it.
