The data from Tom Droege's recent experiments show up some 
interesting trends when graphed.  Below is the graph of his 
latest experiment:

At first is seems that the points are nearly linear, but when a 
four-day moving average is plotted, it is clearer that something 
interesting happened around day 8 and day 14:

When this is plotted with better resolution, it appears that the 
first portion of the curve is concave downward (like an 
exponential reaching an asymptote), then a new exponential 
begins.  Day 10 is Sept 19, the day he switched to 20 second 
recording intervals.  Maybe the changes in the curves are 
related to that, or maybe not.

I also graphed a previously reported experiment:

This one has a very curious shape.  But note that in the linear 
region the slope is similar to the latest experiment.

One thing I get from these graphs is that the system may have 
some very long time constants, either in the servos or in the 
CNF device itself.  Both graphs show some interesting events at 
around 5-day intervals.  This might suggest running the 
experiments for a bit longer, and perhaps reducing th e frequency 
of the source in/out cycles.

(By the way, Tom, I now have a semi-automatic way of producing 
graphs like these from spreadsheet data.  It is certainly not as 
good as real graphics, but it beats just numbers.  If you are 
interested in posting graphs like this, I can send you a copy of 
the spreadsheet.  Or you could post more X-Y data and I could 
occasionally post some graphs.)
