[CQ-Contest] How many hours do SOAB entrants actually operate?

[kr2q at optimum.net]

Toivo, ES2RR asked how many "iron men" there are. 

Here are the "iron man" results from a recent CQWW SSB contest.

First column (left) is hours operated (2 hours groups).  

The second column (middle) is number of entrants

The last column (right) is the percentage of those shown
(which is limited to SOAB entrants only, all power groups, assisted or not).

"0" in the first row means "too few QSOs over too many hours to calculate."

I don't know the algorithm used to calculate non-operating hours.

Hope the table below "lines up" OK
