FLASH reprogramming in the new devices is intended for software updates,
not for general nonvolatile data storage.
1,000 times is a fair number for software updates.

The old devices had EEPROM with up to 1,000,000 re-programmings. Even
that may be not enough for some applications.
I already used a method of storing and updating the data in RAM and
copying to FLASH only when detecting a power-off.

Microchip has an applications note about emulating data EEPROM in FLASH,
for devices that support WORD programming (opposed to page programming).
