One should always consider that relatively short time openings with 
anomalous conditions are not very much considered in studies that have 
been developed with the final purpose to establish how a P to P link or 
a broadcast transmission can be realized at best and with a safe margin.
Amateurs that use low power and generally marginal antenna systems, 
more than often base their traffic just on those peculiar conditions 
(i.e sunrise and sunset or summer E layer multihop) that are not of 
primary importance for other kind of traffic that uses larger power and 
available antennas.
