Complete and total garbage.  Reading from EEPROM and Flash both DO NOT
WEAR.  It is the erase+write cycle that wears them.  Further typical
EEPROM life cycle is ~1M erase/write cycles.  If you wrote it every
minute you could conceivably wear it out in a couple years...but thats
flat out not how it works.  The EEPROM, if any, is not going to be
used for statistics data....maybe fail counts of some kind, lifetime
(hours) maybe...that sort of thing.
