The math behind the “Effectivity L”

[ArvinLar]

You are missing at least one additional factor involved in the math...
min (Strikes / Signals(s), Signals(s) / Strikes)  
...but please note:
These calculations for the Stations listing on the Blitzortung  website
 are discussed and debated (extensively) 

at
https://forum.blitzortung.org/showthread.php?tid=1261


One purpose of these 'effectivity' figures is to indicate when a station
may be sending a lot of 'noise' or 'interference' signals in relation
to actual strokes, both within the region, etc.

Note also that the 'effectivity' figures on the Stations pages
use a different 'computation' than the 'efficiency' number on
the stations network efficiency table at Lightningmaps.org.... again, more confusion.

Cheers!

Hi Mike

Your reply added the missing part of the math. Thank you very much
