George, one of the aspects of how I ranked you and Mark (and, really, in the end, I think you guys are basically neck and neck) was how certain I was that Mark could play well on DK3 if he ever tried. If Mark could get 1m+ on 5-man settings in like under a month (and, I honestly think he could), then it actually significantly matters whether or not he even cares about playing the game. There may be a big element to this debate about actual vs latent scores/abilities and at what point do you not factor in latent abilities that could easily and quickly be tapped. If he could get 1m in a week, is there a good argument? How about if it took a month? A few months would start being too long IMO. See what I mean? This would all apply to my ranking of Dean as well. It's all pretty iffy with Mark even moreso, since I haven't seen him play DK3 specifically, but I know he is great at mastering diverse games in general. So I'm kinda going on a little inductive speculation, I'll admit.
As far as the weighting of the games goes, from what I know of the games, I think a more fair weighting of DK:DKjr:DK3 5-man would be closer to something like 6:5:4.
Edit: Thinking about it now, for the 'latent abilities' argument, what would matter most is actually attempts and not time. So that would probably work against Mark a little more.
