The logic here is median, however the zero days are not included as you point out. Zero days are really “no data”/null days (subtle distinction vs. 0 values) and are not included in the median calculation. Thank you for pointing out the issue here. It is an edge case (accounting for days with no data before calculating the median) and we don’t have any immediate plans to change the calculation logic here. There was no change in the logic on the new stats page; this is the same behavior as in the past.
