Dude, it's real simple. I don't believe that you got 300 at almost 2 a ball on Legend difficulty without some kind of "trick". Whether it's that you quit and reload if you get out, whether you've got some kind of trainer running, whether you've messed with the other teams in career (actually, that's an interesting point, what happens if you turn EVERYONE's skills and attributes down to zero, except possibly your team? The normalisation would probably get messed up by that kind of distribution).
I said I would lose interest if I didn't actually earn my scores. Clearly that's not true for you - because there's no way I'll believe you earned those scores without seeing either the Big Wheel for the whole innings, or video.
Let's be clear, the first 50 were at almost 2 runs a ball. On legend. You've found some kind of exploit, I just wish you'd share it with us all because there might be some hints for people who want to play the game properly in there (exploits can lead to a better understanding of the underlying systems)
I'm disappointed you feel that way, man. I did see your point: that it was clearly possible for someone to exploit the save game function in order to get a big score. I was simply saying that I have a little bit of respect for people who are willing to go to that kind of trouble - largely because I find myself completely unable to care about leaderboards. I want to beat my last score, not yours ...
