This is true, but it misses a very important problem.

Noise.

Super exec might increase profits by more than normal exec, sure. How are you going to identify them? There's actually no way. All the ordinary selection criteria cannot be sensitive enough to sort the wheat from the chaff. Prior experience? They probably only had the job once. Recommendations? Passing the buck. Whiteboarding? LOL.

Chances are you will end up randomly picking out of a group that's mixed super and normal, and chances are you will end up with normal.

If you pay for super you will almost surely be overpaying.
