Okay, so here's some more easily interpreted numbers. In addition to having the largest change in traffic share relative to its previous share, Linux actually had the largest change in actual traffic share. It was just BARELY above Mac OS. If more significant digits were allowed here, Linux rose 0.0085 while Mac OS rose 0.0082.

2022 percentages computed as:

share_2022 = share_2023 / ( 1 + relative_percent_change )

and percent change computed as:

absolute_percent_change = share_2023 - share_2022

* The relative percent change for "other" is not reported in the graphic. There is a remainder of 0.005 in the Share Change which is, presumably, attributable to change in the "other" category.

Last year's results

I just found last year's results. It looks like my math bears out, though it appears that they rounded differently.

Notably, last year's changes were very different.

** Linux and Chrome Book's absolute change was less than 0.0005.

*** As with 2023, the percentage change for "other" is not reported in the graphic. There is a remainder of 0.012 in the Share Change which is, presumably, attributable to change in the "other" category. This seems large, though, given that the total traffic share for "other" is only 0.016. That would imply a change from 0.001 to 0.012. Looking at the 2021 numbers this doesn't appear to be correct.
