Having the same power value for 2 different steps is something we can
expect (although docs say that we expect the line to be monotonically
increasing but anyway), having the same step twice is way out of spec,
there is no way we can have the same step twice on EEPROM, only if we
have a corrupted EEPROM (we need to add some sanity checks indeed here

to handle such a case but first we need to have a "default" eeprom
dataset to fallback when we get such errors).
