I will 'third' Joseph's score.
I'll forgive George on the "1.1 in a week" post though because I don't think he's ever played at 1.1 pace, and doesn't realize that not only is pure skill just one of several factors in getting 1.1, it's probably not even the most important factor.
In fact, I've always felt that there will never be more than maybe 5 more players to ever do it, aside from the 4 (Hank, Vincent, Jeff, and Dean) who are there now. Ross would be one, I can see Dave being another, but that list just isn't gonna grow like the million list will (let alone the kill screener list).
And I wouldn't be surprised if nobody other than the names I just mentioned ever takes it to 1.15 or higher.
When it comes to getting scores that high, it's more a matter of persistence, stamina, patience, psychology, etc. (like Mitch said), and your ability to access your "A" game often enough to increase your chances of your "A" game coinciding with DK giving you the "A" luck that you need. Every plate has to be spinning at the same time. This, I think, is one of the reasons why Hank is such a beast. He seems to be able to tap into his best more than most of us.
I almost never get to see my "A" game. And I won't even know when it's "my time of the month" until I sit down to play and discover that my blood is stone cold DK. Other times (well, most of the time), I'll be trying as hard as I can but won't get jack.
It seems to me that Ross (no offense Ross) is another player who often has to struggle to find his "A" game. When he's on, he's on fire, but the fire isn't always lit.
