And I think that's what's missing from the lube test that is the subject of this thread: How the lube stands up over time (as the solvent dries) and especially with exposure to contaminants. I personally want something that cleans up well and does not leave any non-lubricating residue. And, when combined with soot and range grime, does not gum up. All of the lubes are reasonably good at lubricity if you don't let them dry out, but not all perform well over time (longevity) or when they get dirty. And that is really the only thing that matters, in my opinion. (cold/hot weather performance matters, too, of course)
