I worked on this for a bit with Myth and this is what we have:
This is mainly Myth's work (obviously) Thanks Myth

Squads start off with 1000 rating points.
When a TWD game has been played, the new rating of the squad will be determined by the following formula:
New Rating = Old Rating + K(WP)
P = Probablitity of winning
K = Maximum rating change
W = 1 if the squad has won, W = 0 if the squad has lost
P = 1 / (1 + 10^(difference_in_ratings / 400))
K = 50
Example:
wolvencreed (rating 1000) vs Pallies (rating 1400)
first we'll calculate the probability of winning of wolvencreed over Pallies:
difference_in_ratings = 10001400 = 400
P = 1 / (1+10^((400) / 400))
P = 1 / (1+10^1)
P = 1 / 11
P = 0.09 = 9% chance of wolvencreed winning over Pallies.
then ofcourse, the chance of Pallies winning over wolvencreed is 10.09 = 0.91 = 91%
 Scenario: wolvencreed wins!
so, for wolvencreed: W = 1
new rating = old rating + K * (WP)
new rating = 1000 + 50 * (10.09)
new rating = 1000 + 45.5 = 1046
for Pallies: W = 0
new rating = 1400 + 50 * (00.91) = 1400 + (45.5) = 1354.5 = 1355

K (maximum rating change) is set to 50 in this example. We're considering to lower K when a squad plays more games.
This is info concerning calculating the rating points for TWD. The quote was taken from an ancient post by Overstrand, and Guano thought it would be a good idea to sticky this, because enough people question about it every so often. So instead of staffers giving you a halfassed answer about it all, you can check it out here, if you didn't already know how the rating system works.
This is also a great way to maximize the points your squad can earn, whilst comparing the amount of points that can be lost to any given squad.
