Wellp, I hope it’s not typical behavior, but I worked for a Chinese-owned company (POS equipment), and I was given the task of detailing specifications for a new doodad. Did they have any spex? Nope, just make ‘em up. Max/min temperature, humidity, altitude, etc. Copy spex from different equipment from the same company. Copy spex from competitors’ equipment. Nudge the spex “a little better”, though. Instead of 10%/90% RH, make it 5%/95%. And so on.

Hell, they’d rate a sugar-cube to be water-resistant to 100m…

So who knows. Maybe they just wanted to “up their game” even if only on paper. That’s why I wait for reviews…
