The math behind the “Effectivity L”
#1
Hi

I been trying to figure out the math behind the “Effectivity L”.
 
Unfortunately, I must admit that I don’t understand the logic. Please take to look at my attached image of the danish Station list.
 
I got two stations “Vejle l” and “Vejle ll”. In my logic the effectivity of “Vejle l” is better than the effectivity of “Vejle ll”.
 
Also, the top station shows the right percentage calculation while the percentages indicated for both the Vejle stations apparently showing incorrect values.
 
Top station:
strikes/signals x 100 will in real calculation be equal to: 275/839 x 100 = 32 %

Vejle ll:
strikes/signals x 100 will in real calculation be equal to: 170/493 x 100 = 34 %
 
Vejle l:
strikes/signals x 100 will in real calculation be equal to: 166/360 x 100 = 46 %
 
 
Does anyone have the mathematical understanding to explain the logic behind the percentage values listed in the attached station list? And if so, would you please explain the math and show a full example?
 

Best regards,
Arvin
