Not necessarily, I believe cells can read high just as easily as they can low when they fail.
Yes I agree but I would be very surprised if a cell that was failing in this manner gave a sensible reading when flushed with dil then took a crap.
The only time I have seen a cell fail high the air reading was way high and it was a R22d used in a miniox.
