I suspect the accumulator check last week left the schrader valve on one or more of the seven accumulators with a slow leak.  Not a big operational deal but there will likely be more couping into the platform motion from pump pressure variations.  I don't know what the pressures in the accumulators are now and it will be informative to check them.  I suspect they are significantly down but next Tuesday may be the soonest I can check.

The attached plot really does not show anything about this but I like to show the daily glitch in the pressure signals as I reported in 19416.  Also, the diurnal likely temperature response of the motor speed is obvious.
