Doh! I must have looked at that a thousand times by now... Thanks!

That said, do you know of any more indepth discussion of this? Like how
does temperature, usage, etc. affect this retention time. Where does
that figure come from? I know it must be a calculated value based on
physical models, but what's the model? (roughly speaking)

If it's an MTBF it'd be a much different meaning of course. Can't
imagine it is, I hope!
