Common knowledge and research indicates around 80% training from 46+ minutes compared to 48. If you want to disregard that information, that's fine. I'm not 10K or better, so apparently I don't know anything.
Sorry to be passive aggressive here, but if you want answers, especially in a game like this, you can't rely on World Rankings. I've seen just as much misinformation that's later been corrected by D.I and D.II players as I have seen great information astutely gained by D.IV and D.V players.
