I like the metrics, a few issues though. Hummer you haven't really seen my (Carpetbomb's) endgame. I think I am as high up on your list in the first place because I come back cold after 2 months of not playing and I out manage fleetwise the game assets in my victory over you. I am sure you remember because you put that as my primary skillset.
I can add a few things to my "profile": like I usually help my team win the game before there is an endgame, I am one of the best team players who isn't afraid to stalemate my front to eco and support others while sending my fleets to save peoples ass. The sheer fact that I can do that against most players is an indicator of a massive skill difference. Setting my aggression as low is only because I am playing coy. Older players know exactly how aggressive I am, I was one of the most intense advent rushers. Rushes get old after a while and I'd prefer to play a non pure rush strategy (I am also a fan of the backdoor tweaking by the devs to phase out this style of play).
Also, I excel at keeping enemy players who have already lost alive, so that they can do more damage to their team via soaking up feed, making poor choices, etc. I like to let them languish in obscurity while the real power fights occur elsewhere. Naturally I will execute them when I need to, I enjoy playing with them like a cat with a mouse.
You could ask the legions of people that have had me literally save their asses from the brink. As for eco player, I am one of the best, yet I am very rarely in an eco position. I excel at long term investments and feeding at the right times, which is a very counter intuitive skillset. I get a lot of suicide spot positions, easily over the average, about 33-40% of games. I do quite well in those spots considering I am usually up against the top talent of the opposing team and I survive past the hour HW still intact with conflict, as advent. Few others can do the same against talent, without feed. Just sayin.
"Higher level" players have their skill thrown off because of feed strategies, the people considered to be better get fed a lot to push their pwnage. I only propagate that I am a horrible ineffectual player because I prefer to not give myself these trumped up advantages(more bragging rights), it allows me to team stack(without the help of anyone else and is very subtle) and people actually believe me(it's fun to laugh at people who just don't get it).
A few notes: Auqia and some others use macros to make their micromanagement better. Macros allows the player to shift their personal resources around so it seems like they are better than they actually are. Macros are a crutch, the time efficiency gained by their use is a hack on the game. Also, similar top players also use well known (to a few) bugs that in a pinch they will use(starbase health bug for Vasari oh my). I am quite good at putting them into those pinch situations and I have seen quite a few "tricks".
To all the players out there that do: If you have to use macros or bugs to win, then you have already lost and we all know it. Go cry on your code, programmer whores.
The top 11 players on your list are the only ones I expect an intense game from. I win those games with regularity.
