I’m a layman but from what I’ve read recently, 92 to 78 is 14 degrees; the typical temperature differential is a maximum of about 20. There may be a few more degrees you can eke out, but you are getting a majority of the potential benefits
While correct, you usually see only a 20 degree difference, that’s between the intake and exhaust. Since it’s recirculating the air that should be able to bring the cooled air down further.

There really isn’t any such hard limit on systems like that.
