If I correctly read the studies on the stainless steel oxidation available online, a complex chrome-oxide film forms within first hours, and prevents further oxidation and rust; its thickness stays the same after that.
What you say about the oxidation rate may have place in rusting carbon steels - especially the red rust Fe2O3.
My estimates and concern are about the stainless steel with at least 13% Chromium content, as this is what the majority of my customers have their blades of.
I set oxidation-related drop in sharpness to 20 BESS, given the 5 units resolution of the PT50B used at my workshop.
