example: for Caramunich III , 160 EBC they give 60 Lovibond

http://www.browamator.pl/zdjecia/3/9/9/7198_Weyermann_Caramunich_III.pdf

While it should be (SRM=EBC*0.508) around 80 Lov

I contacted Weyermann via my LHBS, and I got the answer:

Andreas Richter, Weyermann quality director explains, that they use formula published by Sibel Institute,

Lovibond = EBC x 0,375 + 0,56

I see this formula here and there in the net, sometimes they explain that this is formula for old EBC norm, abandoned in 1991 and should not be used any more.

Can somebody back me up with some knowledge, which formula is correct, so that I could continue the discussion with Weyermann.
