Serious question about this argument. Try translating tenths of inches… to what? I assume you’re not talking about converting to metric because then any unit is problematic, and if you’re using tenths of an inch then you’re using inches, not something else, so… what’s the problem?
I love Proton and will advocate for it any chance I get, but I can also see that it might be good to have people like you who don’t put all their eggs in one basket
