And the problem with generic stereotypes about C41 is not only that some of those films have significantly improved in recent decades, and that in the past, a huge quantity of color neg film processing was done by quickie mini-labs and so forth which really cut the corners in terms of quality control, proper washing etc.
Even with some of the best track records, like Kodachrome, IT ALL DEPENDS on both the quality of the original processing, and especially the STORAGE CONDITIONS, as well as how much projection a slide might have suffered. And overall, "archival lifespans" based on extrapolated 24 hr torture tests in special aging chambers are, at best, informed guesses involving only a limited set of variables. Take em all with a grain of salt.
