-33 is the lowest I've personally decoded, been decoded, and have seen
between others. Currently running WSPR4 in Linux with a Microham MK2R+
(built in USB soundcard).

According to something you said in your interface PDF, the -28 seems to
indicate that I already have a decent sound card (among other
things.) What
do you think?
Probably yes, but my testing was JT65, where -22 to -23 is pretty much
the lower limit at which signals can be decoded. WSPR uses a more
powerful noise reduction protocol that can get deeper into the noise
floor. Check the WSPR doc for what that limit is.
