It took me too long to comment (thread closed), so I'll say so again next time, but for this comment:
"^this means that I gave certain malus for doing or not doing something that was asked for. For example, not providing any WorkInProgress (WIP) has been leading to a malus. That, and also some other points.
That simply because I think it's pretty unfair, if we set up rules, and the ones who always do things correctly get absolutly nothing for it. So breaking in certain rules has lead to malus this time, which means it simply gets substracted from the final score."
I have nothing but respect. Very good of you to do this; finally holding people accountable, and benefiting to who follow the rules. : )
