Efficiency

[cutty]

In the English, the term Egon's using is "Effectivity" on the 'Participants page".  
"Efficiency" is used on LMO.  The difference in terms can be either significant, or similar...

I note most of the posts, and even the thread title is the term
"Efficiency"  ... as in "Skillful use of energy or industry to accomplish desired results with little waste of effort

"Effective" as "successful in producing a desired or intended result".

So two stations at the same location:
Both stations send the same 100 strokes, with good data, good GPS, etc.
Station X sends 200 signals
Station Y sends 150 signals
to produce the exact same result - accurate detection with good data of a lightning stroke-
Both stations have the same "effectivity" -ability to achieve a desired result.

BUT  X is less "efficient" than station Y which sends fewer signals.
That is, both stations send good info about 100 strokes, X should have the same "Effectivity" as "Y"  but certainly less "efficiency".

So, if those definitions were adopted, the whole issue might be changing the term from "Effectivity" to "Productivity" or similar,
meaning "the effectiveness of productive effort, as measured in terms of the rate of output per unit of input".
