Modification of the NTR computation - Update 2
With the next update of the NTR we'll roll out the first modification, which will reduce the influence of team tournaments. With this update the influence of team tournaments will be reduced mathematical to the same level as the single player events.
Currently a team tournament of size X will grant more points as a single event of the same size. This is based on every team member getting the points of the team's placement. Looking at teams of 3 the first place gets average points for the 1st place ((1+1+1) / 3) while the average of a single event is a 2nd place ((1+2+3) / 3).
The new version will update the formula to match this issue so that every team member will only get the "average points". The placement bonus will also be splitted.
Many thanks to the gamers users who gave us a head sup on this mathematical issue. I couldn't find their names right now. Thanks!
We'll checkout how the rankings will react on this change and decide afterwards wether we need more reduction or not. Due to the modification the NTR won't be calculated automatically in the morning, but during the day so that I can have an eye on what's going on.
Update: Modification is now online.
Update 2: There was an issue with the points on the NTR player pages. The placement bonus was taken into account twice. This was only a display issue. The actual calculation was correct. Thanks to Fenryll for bringing this to our attention.
Upcoming modification of the NTR computation
Based on the running poll about "Team tournaments in the NTR" we're planning to add some modifications to the math behind the rankings.
The current standing of the poll is
* No change: 15%
* No team tournaments: 20%
* Reduced weight: 58%
* No interest: 7%
based on rouhly 350 votes.
So we'll keep the team tournaments in the NTR, but reduce their impact. There are a couple of approaces to do this and we're going to do some math to see how each turns out. Many thanks to everybody who gave some feedback on this.
Working on the math we're (probably) going to simplify the computation a bit and modifiy the weighting factor (WF) so that all 5 results will count as 20% of the final NTR points. This has to be checked with some calculations first.
NTR 2012 without team tournaments - Update
With the latest update to the NTR algorithm (v2.8) we're going to test this year how the rankings develop without the impact of team tournaments. There have been a bunch on controverse discussions on their influence and we'll check this out now. Keep in mind that this can easily be reverted as no results will get lost.
We'll keep an eye on the rankings and would like to get feedback from the community no this. There are a couple of things which could improve the NTR, but we're going to stick to small iterations like before.
Update: I just reverted the change due to the overwhelming feedback. Everbody can see the difference between the two variants in his NTR profile as the "team tournament"-less placement is marked as the previous placement.
I'll start a discussion on how to solve this issue.
