Could some kind soul explain how are the NS calculated? What do the numbers in parenthesis represent?

Thanks in advance

I think is the number of racers who got a pool

8 (26)

26 - the total number of racers from a country (Germany in this case)
8 - number of racers whose results are counted in the standings

30% of racers are counted from each country or smth .

Many thanks for the rapid answer!

And a correct one too
