How do I know? I have an electric monitor which evaluates my useage 10,000 times per second.
Interesting fact a SEER is BTUs per watt of electricity.

It is all at best a GUESS. The 1/3 number that I posted comes from one of those home shows.
I'm sure you will agree IF the unit started at 10 your posted information it is not a 10 25 years later.
My point was if not clear years to recover the cost of replacing the unit.
