FA Stats - is there a second systematic error?

FlightAware ADS-B Flight Tracking

I will admit it has been “fun” to be in the top 10 overall results, but also want to make sure that it is warranted. (hence the thread I started http://discussions.flightaware.com/ads-b-flight-tracking-f21/30-day-statistics-rankings-t36560.html) It would benefit all of us to have a fair and consistent way to compare our results around the globe. I pay more attention to my local results since these feeders have a similar view of the sky.

Cheers!

PS That snowstorm to my east dumped 1 snowflake on my yard, while 50 miles away got 1 foot or more. It has severely dropped my stats over the weekend but did seem to increase my stats leading up to the event as planes were moved around to prepare for the storm.
