I have a carrier unit (Compressor 38TKB030300 2.5 ton (30,000 BTU) R22, replaced 2000 with TXV) and am hoping I could get some help figuring out what the subcooling specification should be?

Currently I believe it is at 28 degrees. Readings from yesterday in the spreadsheet photo.

Then here is the label on the outside of the condenser unit that I think says subcooling should be 11 degrees.

Then here is a PDF that says subcooling should be 20 degrees on page 3.

Then here is a picture of the label on the inside panel that tells me to calculate things in terms of superheat. I'm assuming this is OBE because of TXV.

Either way I think I'm over charged but wondering if anyone has a definitive thought on what subcooling should be?
