DISCLAIMER: This achievement requires a lot of dedication and a full party of 4 diferent gamertags. It's a long journey and at the time of writing this the top place in the leaderboards has around 780k win points. Seeing that you get 6.030 win points per match and each match takes around 20 minutes, you decide if you want to commit to this or not.
UPDATE: (10 Set 2011) The top spot has currently 1.060.000 points.

The boost itself is easy but time consuming and depends on a glitch:
1. 3 people must organize a party and select Ranked > Arena CTF > Endurance, and the solo person (referred from now on as the "pointman") does the same but alone. This ensures that it will be a 3 vs 1 match. Note that the person who is in the process of getting to the top of the learderboards must be in the party of 3!
2. There are 4 maps:
Speed Trap  It's the ideal map. Takes minimum of 14 minutes and has a pit. Relativity  Good map, takes minimum of 16 minutes and has a pit. Death Before Dishonor  Good map. No pit. Heartless  Good map. No pit.
3. In the party of 3, 2 people (the ones not going for the Number One achievement) must commit suicide 100 times, making their score (not win points, SCORE!) "100". Make sure not to kill the pointman, not capturing flags and not even touching the flags because if you get one point for anything it'll be impossible to get "100" in that match. Just suicide and don't do anything else. Pits are ideal for this. On Speed trap it's easy to find the pit but on Relativity it will take a while to memorize its location but you'll get it eventually. If you don't have a pit you need to kill yourself with weapons that have splash damage. The best one is the Hyperblaster. Bring it on top of a Scout or Ammo Regen rune and it'll be even faster to kill yourself and when you get back the Hyperblaster will be right there again!
4. The other person in the party of 3, (the one going for the Number One achievement) must proceed to capture 9 flags from the opposing team.
5. After 9 flags captured, the point man picks up the enemy flag and brings it to his base but doesn't score it! The person going for Number One should pick up the Doubler rune (to ensure faster kills) and then starts killing the pointman while he has the flag held and scores 3 points from a single kill. The pointman respawns and picks up the flag, that should be in his base, and the Number One person kills him again for another 3 points. Repeat until the Number One person has 195 score (not win points, SCORE!). If by any reason your score doesn't reach 195, you can kill yourself to remove a point, or if it's below 195, you can kill the pointman without any flag holding for 1 point per kill.
6. Final Step, if both suiciders have "100", the Number One person grabs the enemy flag and scores yet again making his score 201, and the glitch will concede 6030 Win Points.
7. Just to sum it up. You get 54 Points for the initial 9 flag capturing, then you need to kill the pointman 47 times, getting 141 score, plus the 54 from before, you'll reach 195. Then, you score the last flag you'll get (1+5) points for it and reach 201. If both suiciders have "100", you'll get 6030 win points.

8. A small tip:
195 is a multiple of 3 (65 * 3 = 195). To see if your current score will reach the 195 mark, you need to know if it's a multiple of 3 too. For example, imagine you have a score of 117. That's a multiple of 3 (39 * 3 = 117). But 118 is not. Since you get 3 points per kill you need to guarantee your score is a multiple of 3 everytime.
To do so, make a sum of the numbers in the score and see if the result is a multiple of 3.
Example:
117 > 1+1+7 = 9  Good! 9 is a multiple of 3. 156 > 1+5+6 = 12  Good! 191 > 1+9+1 = 11  Not good.
And so on...
This tip is simple math applied to video games.
If by any chance you didn't understand, just ignore it. =)

Sorry about my grammar, I'm Portuguese, therefore not Englishnative. If you spot any bad grammar or simply a concept not explained correctly, tell me please.
Good luck!

Additional info:
 You don't need the Doubler to score flags or to get points. All it does is help you kill faster since you deal over 100 damage with a single Railgun shot or rocket.
 You don't need to get 200 suicides and 201 points. You simply need to have 1 more point than the total number of suicides, so you can do 300 suicides and 301 points, or 237 suicides and 238 points. It always works and the win points you receive is 30 per suicide + 30 win points for winning the match. (Example: with 286 suicides, you should get 287 points giving you a total of 286 * 30 + 30 = 8610 win points).
 You can get extra negative points if you kill a friend, which means, you can shot your team mates with the machinegun (other weapons are not guaranteed to work) making them fall into a pit and it will say that you killed you friend getting you 1 score for that.
