Typically there are quite a few, and over time it would build up data
points. Since WSPR is a weak signal mode, the antenna question is moot. A
simple script might be able to be able to be written to either switch
antennas at different transmission cycles, or to key different rigs. I like
the idea of switching antennas as that takes the rig out of the possible
variables - even though it is probably in the noise.

Yes, with any evaluation of antenna performance, more data from more points
over greater time is better.
We did what we could easily do without that automation. I don't know enough
about WSPR to know the extent to which two QRP rigs at the same site could
TX with different callsigns in alternate transmission cycles.
Another limitation is the number of WSPR stations active on 80M with
antennas good enough to hear us.
