OP, I think you mis-stated the definition, in googling around for it, I'm not finding that second clause applied to cycing - which makes it make more sense (not that it makes much sense, but at least it's not total nonsense.)
http://en.wikipedia.org/wiki/Arthur_Stanley_Eddington
"Eddington number (cycling)
Eddington is credited with devising a measure of a cyclist's long distance riding achievements. The Eddington Number in this context is defined as E, the number of days a cyclist has cycled more than E miles[5][6]. For example an Eddington Number of 70 would imply that a cyclist has cycled more than 70 miles in a day on 70 occasions. Achieving a high Eddington number is difficult since moving from, say, 70 to 75 will probably require more than five new long distance rides since any rides shorter than 75 miles will no longer be included in the reckoning."
It's a more-or-less identical definition, except that the part I added is intended to state that
E is actually the
maximum possible value for which this definition is true. (Otherwise, if you have
E=50, for example, you also, by the same definition, have E=1, E=2, E=3, E=4,.....) My definition is more mathematically rigorous, but also, apparently a whole lot more confusing.
Note that the very next sentence in the Wikipedia article you quoted states that this is the same as the definition of the "h-parameter" used to evaluate scientific output--my definition is based on a description of the definition of h-parameter.
