If you still don't understand the question, heres an example.

I just looked on the packaging for my P121M (medium) and it says ND4 which I had assumed means 4 stops reduction in light at the darkest (top) of the filter but looking at the table in the link above it appears to be 2 stops. Confused?

ND 2 = 1 Stop

ND 4 = 2 Stops

ND 8 = 3 Stops

Cokin 121 L = 1 stop

121 m = 2 Stops

121 S = 3 stops

Hope that helps.

Its whole new world Smile a 121m is indeed a 2 stop filter

Thanks, it does help. So then how many stops is the 0.9 ND filter from Lee?

0.9 = 3 stop

0.6 = 2 stop

0.3 = 1 stop

I prefer the Lee way myself.
