Frequently Asked Questions » Matchratings explained - the stars unfolded
Its been a mystery and often have people asked themselves how the f**k we come up with the match ratings the way we do.
I'm happy that i can now put a large portion of that to an end - we are finally confident enough with the system that we will make it public.
The Basics:
The ratings depend to 95% on the tv viewerpeak that everyone can see below the server listings on the matchpage. We constantly calculate a scale that puts matches with most viewers into the 3 star area and adjusting everything else according to that.
The Math:
1. We find the match with the most viewers in the past 3 Month - thats currently an allstars match with a viewerpeak of 906
2. We take the square root of that number to get those top scorers a little closer to reality ;-) - thats about 30 atm
3. We devide this area into 10 ratings - 1 is 0-3, 2 is 3-6, ... 10 is 27 to 30
Thats it basically - if we have a match, we take the square root of its viewerpeak and check into which area it falls, giving it a rating from 1 to 10 (internally)
This rating is then translated into stars in the following way:
1: 0 Stars
2-3: 1 Star
4-6: 2 Stars
7-10: 3 Stars
Some numbers:
Again based on current figures (for et only) (and they change constantly) this is how it decides
0 - 20 viewers: 0 Stars
20 - 110 viewers: 1 Star
110 - 380 viewers: 2 Stars
380 - 900+ viewers: 3 Stars
So you got a time machine?
No we don't - although we'd like to simply look into the future and check how the viewerpeak will turn out we can not :-(
Viewer peaks for matches in the future are estimated from statistical data gained from previous matches of the same teams or in the same league. In most cases this is pretty accurate but as you have probably noticed already gtv sometimes adjusts the number of stars up or down during or after a match (when viewerpeak is known) - especially for borderline cases.
So next time you see "lol X Stars" in the comments, just link them here ;-)
