Remember that the 1000 is a minimum over the part's temperature range- the
Flash cell endurance goes down significantly as temperature increases, so
the minimum number of erase/write cycles given (1K) is is worst case when
the part is hot. Getting the Silicon to do 1000 cycles when hot leads to
the part lasting through *A LOT* more cycles out of the flash cell at room
temperature.

Rule of thumb here: don't do your programming cycles with the part in an
oven.
