UKC

I know it's all subjective to conditions and quality of gear ect.
But how would those in the know convert/compere M6 to a scotish grade.
Eg: would M4 become say scotish IV
Thanks in advance for any replies.

In reply to Diggler: I think the very rough chain of thought is you add about 1.5 to the M grade to get a very rough Scottish Grade.
So M6 would by VII/VIII. I think.
