I have conducted a variety of experiments simulating inefficient
compressor (with all else functioning properly), and the result
was low compressor inlet superheat (and/or hunting) every time.
You really have me there. I am rethinking things.

I still cannot envision a captube system behaving so. I apologize to guestingmale, but he started this and most likely has fixed his problem without regard to the discussion he envigorated.
