The script still assumes constant ingress patterns, but unfortunately ingress has dropped quite a bit since June. So I think it’s doing exactly what it’s supposed to do. Thanks for reporting back though, this confirms my calculations are actually matching real world behavior (when corrected for changes in ingress). If only I had a crystal ball I would correct for future ingress patterns too. 
But for now this will have to do.
I think the topic you referring to is the one I also linked in the changelog post: Intro to the Web Dashboard - #6 by BrightSilence
