Hi,
I think that elephant counts PFR twice when a player raises twice preflop and therefore there are sometimes weird situations like PFR 150 or so 
Example:
Player A has played 3 hands yet. In the first two, he openraised and everybody folded. In 3rd hand, he openraised, player B 3betted him, player A 4betted and player B folded. Player A then has 100% vpip and 133% PFR in elephant.
It occured in every version of elephant i've ever had.
Cheers, lolofon
