You are correct, but McCarthy et al. (2010) says: "The experiments revealed that a sharp blade (i.e. a virgin surgical scalpel blade) had a BSI of approximately 0.2 while a blunt blade (i.e. an artificially blunted blade was used) had a BSI of approximately 0.5. These values gave an indication of the upper and lower bounds for both sharp and blunt BSI values, respectively".
Based on this quote I would expect that BESS score 50 gf corresponds to BSI index of some 0.2.
ad b)
As far as I know only the EOU support document entitled: Additional Information That may be Relevant and Helpful to the Advanced Sharpener and Edge Tester.
