Hi Andy,
 
>> 2) There is a gap in plentiful station locations from those around 2000km (Eastern and Northern Europe) to the next group of US ones at 5000km +
That gap is also known as the Atlantic ocean ;-) Seriously, it would help if more stations from eg Russia or southeast Europe were monitoring.
 
>> 3)  WSPR-15 does not have 9dB advantage on longer paths due to propagation artefacts.  Perhaps fading and breaking it up.
Don't know, we'd really need a side by side comparison to draw quantitative conclusions. Your announced dual-speed beacon will probably some good statistics, or alternative we might resort to path simulations. My guess is that fading may generally be much less severe for very long distances than for medium ranges. 
 
All the best,
Markus (DF6NM)

Here is a list of all the WPR-15 stations who have heard my beacon signal within the last few days.   The maximum distance of 1900km is about the same as the WSPR-2 transmissions made earlier this year at the same EIRP.  I'm guessing there are a several reasons here:
1)  These summer months give reduced S/N / propagation and offset the theoretical 9dB gain
2) There is a gap in plentiful station locations from those around 2000km (Eastern and Northern Europe) to the next group of US ones at 5000km +
3)  WSPR-15 does not have 9dB advantage on longer paths due to propagation artefacts.  Perhaps fading and breaking it up.
Anyway :
