All I am talking about is the Current stats- the yellow section and
whether or not it "resets" when hitting the "Clear Current Stats"
button. It appears that it doesn't, unless Montrol is restarted.
Here is a screenshot of the incorrect calculation on 7 samples
Looking at 7 samples in the e-08 and e-09 range, an average in the
e-04 looks wrong without even working the numbers :)
and here is the manual version with the worked numbers:
9999999.87500000000000000 -1.25000000000000E-8
9999999.62500000000000000 -3.75000000000000E-8
10000000.31250000000000000 3.12500000000001E-8
10000000.06250000000000000 6.25000000000001E-9
