As far as people using steam on linux, who participated in the steam hardware survey?

Presumably, since the percentages for the displayed 4 Distros don't add up to the total usage. Which means there are two conclusions. survey results are bugged, or they are only displaying the top 4 distros only, and all the other distros (like me on Nobara) don't make some arbitrary cuttoff for listing. Which makes since, since Manjaro and Linux are at the bottom of the display with only .07%.
