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.
