p.1 #1 · B&W filter question

I have recently recieved a B&W filter that is a graduated neutral density filter. It has "25%" rating on the metal ring. Is this a 1\2 stop,2 stops or less? I am used to .2,.4,.6 on ND filters. I can't find any info on this. Does anyone know how many stops this filter is? Thanks for any info.

that version says it transmits 25% of the light so maybe thats the 25% on your ring? in which case it would be 0.6 (2 stops). Not 100% sure though
