(Expecting FabledIntegral to jump all over me too...

)
49 games, 17 wins 1511 points (but with an 8 players doubles win to be added tomorrow. Oh yes indeed).
I'm fairly confident I can make 2,000 points before 100 games are played, simply because the kinds of games I play and am pretty decent at can give you lot's of points. I play 8 man doubles on 2.1 and will be 3 wins and no losses by tomorrow, and if I can just jump in ahead of FabledIntegral, I am well aware I need to finish a few more games before that stat means much of anything! I also play six man or 8 man singles games as well. If I can keep my win percentage above 35% I will make a lot of points.
I also have an advantage in that very few high ranking players join the games I play in. A major is a rarity, a colonel a surprise to all concerned. Assuming that top players will in general play a little better, I may be a touch fortunate in that the average player in my games is probably a sergeant. Yet I find most 2.1 players play that map pretty well regardless of rank. There are a lot of players out there who play a lot of 2.1 public games (some almost exclusively) and I would suggest it as a map to play on if you want to improve your score. The reason is very simple: even in an 8 player singles game (flat rate, sequential), it is possible from any opening position to secure a small base and start expanding. If you know how you should expand from say 'The Horn', you have a pretty decent chance of winning the game. No early losses on this map, anyway.
I'm not sure I agree with this 'wall' concept. Risk is a relatively simple game and I suspect the difference between a lot of players is, to a great extent, about how hard they are concentrating on each move. I usually take at least 5 minutes to study the map before playing and if the game is at a key point, I may glance at it through the day, ask for opinions on the position from friends and in general think about it a great deal. I suspect a lot of players don't do this. However, I only play about 8-10 games at a time (what a waste of premium, I know!) and I am positive my win rate would go SHARPLY downhill if I was playing the 50-100 games some of the top players are playing at one time.
So, I think 2,000 points is within my reach, but 3,000 seems a very long way away, impossible to achieve even, and I have the greatest respect for the players who have managed such a high score while still playing within the rules and the spirit of the game.
