In the comment at the bottom it says: bcrypt work factor is 5, scrypt work factor is N=1024 r=1, and PBKDF2 rounds are set to 1,000.
If they did indeed use a work factor of 5 then this analysis is pretty much meaningless for bcrypt. The default is 10 and I usually use 12 myself.
107 kHashes/second/machine for bcrypt in default settings (which probably many sites will use).
