Question re:Max Demand and Power factor

1. Can you explain to me just how "Max Demand Works" Your new "Dash" software seem to indicate that it resets. Software shows a count down to reset. How does the 15/30/60 intervals work. Average ? over the interval? Does Max Demand mean (=) Peak Demand from the last time it was Zeroed?
2. Just for chuckles I set it to 15 minutes. Max Demand went higher than I have ever seen it before ?
The other interesting fact I noticed is that In the year or so I have been tinkering with my EKM I have never before had a capacitive power factor. My power factor has alays in the pass been inductive. Currently shows L1 C95% and L2 C63%. To the best of my knowledge all my stuff should be inductive. Refrigerators and Freezers.
The other anomaly I noted is the L1 & L2 watts don't compute.
As I recall Power (Watts) = Volts times Amps times power factor. I don't get the same numbers that the EKM does.
