Appreciate the confirmation. I actually checked GamingOnLinux before doing the math, but they hadn't updated their graphs yet for March.

Since I did the math correct the first time, I'm going to double down and math again!

Non-Steam Deck Linux % for English Language: 8.63%

Math: (Linux English / Overall English) * ((Linux Overall - SteamOS Linux % of Overall) / (Overall - SteamOS Linux % of Overall) = (82.75% / 39.09%) * ((5.33% - 1.30%) / (100% - 1.30%)) = 8.63%

SteamOS Linux % of Overall = Linux Overall * SteamOS Linux = 5.33% * 24.48% = 1.30%

Assumptions: % of English Language usage is uniform across all Distros; Probably another assumption, but it's not coming to me right now.
