[CQ-Contest] The VOACAP mystic

Just to spot the last article of a long series published on my blog, 
which shows the discrepancies that can be observed between VOACAP 
predictions and real SNR measurements.
The measurements have been done using K1JT's WSPR which provides near to 
the dB accuracy on SNR measurements.
A few DX pathes like 40m ZL/F (almost antipodal) have been studied over 
a 3 weeks period, both at long and short path, which produces a quite 
accurate "smoothed" curve, that can easily compared to the VOACAP output.
So not a real contest topic but I think "of interest" for a majority of 
contesters...

To make reading easier, a summary is available at
