Has to be extra files it found from 10.5 and 10.6 and lots of log files, I doubt its nothing to worry about, also I know 10.6 rounds the numbers diffrently it uses base tens and not the regular system where each 8 bits is a bite or something
Honestly I would be be concered because there is nothing to go off, Just be happy!
well unless you are missing files, are you missing anything?
