Best fit to data (blue line). Reference gradient (red lines):-8.6ms/day/mbar.
Going varies with pressure because of drag, added mass and buoyancy. Barometric compensator fitted 28 March 2010 should fix this.

- nothing to report - just enjoying 2 weeks during which the clock has lost only 0.5 seconds. Not sure why the recent slowing down - temperature compensation is ok [link] , still not certain about the barocompensator [link] but there is a lot of noise on the plot. The biggest effect at the moment is draughts, I think, caused by differential temperature with the centrally-heated room below. As spring settles in we should see less of this.
