Well, apparently the fail point is about 8hrs under normal circumstances - that is up to 8hrs after applyiing right after shower and letting air dry completely. (on re-apply: about 3-4h)
Under stress (nervous, rushed, etc.) it did not perform as well as, but that may be expected.
Overall, so far Id rate the HP to be about 80% compared to commercial deodorants, but so far the first to allow me to go over one week now without giving in.
