No, I think Paul explained that quite well and from what I have seen in the few games I have played since the patch, I can see that it is fairly balanced.
Firstly, you have to work your way into the next tier. It's not going to change with each game.
That means getting a certain level of consistency in your game to get enough match points, but then measured against difference scales depending on if your team won or lost.
Looking at the numbers, it is just as easy to lose your rating as it is to gain it.
Here is what I have found.
VICTORY
Get a match score of at least 100pts to get an increase. The increase here may not be much and I expect a player with a higher score would get a more significant increase.
Scored under 100pts in a victory and there is no change. So if your team carried you through the battle, you will not be punished for a poor game, but neither will you be rewarded.
DEFEAT
You need a match score of 300pts or more to not have your PSR affected.
Edit: it appears you need a match scored of 500+ to increase your PSR while on the losing side. (Thanks Be Rough With Me)
If you get a match scored under 300pts, your PSR will drop. Once again, the amount of change looks to be a bit of a sliding scale and may vary.
It seems to me that this is fairly balanced and a decent system where we will see players who regularly score 300pts or more a match move themselves into a higher tier where they will face similarly skilled opponents thus making it more difficult to maintain or raise their PSR.
In addition, with the testing for new mech quirks that was started, expect to see a change in the way points are rewarded so as to better identify and recognise the efforts of players taking on a different role.
That is why a team that performs well together will likely win and most likely have decent enough scores to advance their PSR.
This system has only been in place now for 2 days. It will take a little while for the segregation of players to occur and then we will get a clearer picture of how it is going.
