Great, these are very good benchmarks for me. Note though that his
statistics are for 4-character passwords as opposed to cRARk's (and
mine) 6-character ones. The RAR format suffers bad from each extra
character and showing 4-char statistics is just silly as you will
exhaust that keyspace in half a minute.
