I'm working right now to release the first batch of data (550k records).
It is interesting to note since I started to fetch the data in Monday the ID number increased from 4,973,649 to 5,009,849.
That means 36,200 new profiles boot the game for the first time.
Total profiles: 4,009,850
Is this compiled/cumulative data of yours showing us that there's a shy over four million copies of Gran Turismo Sport out into the wild?
Honestly, I am super-duper impressed!
