The last PES stats cured by japanese team were the 2014 ones. As you may know, the stats system was changed, with new addings (Attacking Prowess, Defensive Prowess, Ball Winning), but as you may know additionally, these stats were just a calculation from the previous Attack, Defence, BB and Response values.
Starting from this, I've just made some calculations to find out which were the actual old gen values which were afterwards trasmuted into the new values. PES 2014 had also a PS2 version with old-gen stats, but it didn't received of course the later updates that followed from month to month.
The calcle was simple as I already had the BB value to start with, so I've found out some very interesting stats.
If you want to know about some players in particular, just give an ask. I'm currently creating a small ladder into I'm putting the values I extrapolated since now.
