How is this Site Speed Page Timings Average Calculated ?
The average I'm trying to wrap my head around is in red in the pic.
First, I averaged the Avg Page Load Time and I got 20.23 instead of 21.65.
Then I tried a weighted average, using pageviews as weights and I got 21.45, Still not right !
Finally I retried using a weighted average without the rows : Guelmim-Es Semara, Tadla-Azilal, Taza-Al Hoceima-Taounate since their Avg. Page Load Time was 0. With this method I got to 21.62 Close but no banana.
Or is this a rounding error ?
