Jon,
Love your work!
There must be an issue with the chart summary setup. Yesterday there was no data showing for Nov 2 and the total value for Nov 1 was higher than the raw data showed. Was showing 6:27 run time, but today shows 4:36 total.
(top) Graph Nov 2 approximately 1:00 PM Eastern Time
(middle) Graph Nov 3 9:00 AM Eastern Time
(bottom) charted it myself yesterday from the export to make sure I wasn’t missing something
