Interesting. Any idea why an SSN of 21 was (apparently) used? If the
analysis was done with a VOACAP-based tool, the NGDC SSNs are recommended,
and the value there for Oct 2008 is SSN = 6. Using a higher SSN would
probably bias the results toward higher frequencies.

VE5ZX and friends have put together an interesting matrix that shows
propagation between CQ zones.

That will give you some idea of what bands are open to where and when.
