Thanks Turrican and Christian!
I'm still not clear how TPP are calculated. It's says what is below at the link you provided, but it doesn't say how TPP are calculated; or, doesn't appear to.
My overclockers league points are 327.6; my UP is 411.6. The league points are lower than the UP points because only the 15/20 best scores count.
But, my TPP points are 1030.7. Why are the TPP points so much higher than the UP points of 411.6?
"A special type of points featured for the first time in Rev4 are the so-called ‘powerteam’ points. Powerteam points are nothing more than global and hardware rankings, but instead of grouping results per user, the results are grouped per team. This means that the Powerteam rankings are mainly a competition between teams, rather than individuals."
