Awesome that you are tackling this issue. I think you fully understand the problem and love how much effort you've taken. I agree specifically about the top 3 bonus for crowns and merits (the SPS isn't my concern).
The math in your formula is over my head, but I trust that it works as you've explained.
Great job and I hope you and @schachoberhessen can get attention on this issue so that the brawl experience can continue to be a driving factor in the game!
Thanks a lot for your feedback.
But I know how to code, so once I have it, the rest is rather simple ;-) To tell the truth, I would have never been able to come up with the formula without @kalkulus - he's the real MVP here.
