There's one problem in deciding how many samples to average when the
sample interval isn't constant. The program makes a best guess for the
number of hours you request, and displays the number of samples as a hint
on the up/down label. It tries to make the exponential decay to a 10%
final value over the selected number of samples. Of course, you can
choose between simple average and exponential average as you wish. You
can also re-process older loopstats for comparison.
I've just uploaded a new version which tells you what image files, if any,
were saved.
Cheers,
David
