Title: Rebase SampleCount stat on the number of datapoints

The SampleCount statistic was tied to the rolling sum maintained
by pandas, as opposed to the rolling count of the observations
received within the window.

As a result this statistic value would generally be incorrect,
except in the special case where the average of the datapoint
stream is constantly one.
