What is GG(x)?
GG(x) Model

GG(x) is the engine that computes metrics such as Performance Rating, Team Luck, and Laning Phase. These metrics are derived from machine learning and a comprehensive statistical algorithm. Results are in a normal distribution with a mean value and a standard deviation with respect to the player's tier and position.

For example, Silver ADCs average 5.6 CS per game with a standard deviation of 1.4. 68.2% of Silver ADCs are within one standard deviation, averaging between 4.2 and 7.0 CS per game.

GG(x) makes a variable out of every event in a game that correlates to a game being won or lost and computes the data in its native function. Results are compared in both absolute and in relative terms to the player’s team and to the opponent’s team for validity. A massive amount of data is continuously updated and computed for up to date analysis and precision.

Key Metrics
Performance Rating

Performance Rating is a numeric indicator of how well you play in a game. The scoring system is from 0 to 10, with 10 being the highest score.

Rating Expected Win Rate
0.6 6% Expected Win Rate
1.7 17% Expected Win Rate
2.8 28% Expected Win Rate
3.9 39% Expected Win Rate
5.0 50% Expected Win Rate
6.1 61% Expected Win Rate
7.2 72% Expected Win Rate
8.3 83% Expected Win Rate
9.4 94% Expected Win Rate
9.9 99% Expected Win Rate
Team Luck

Team Luck measures how well your teammates perform in a game. If your teammates perform very well, your Team Luck score will be high.

Laning Phase

Laning Phase is an indicator that measures your performance until the first turret is destroyed or 14 minutes, whichever comes first. Opposing lane matchup and normal distribution of each position is taken into consideration during calculation.

There are a total of 9 ratings from 9to1 being the highest to 1to9 being the lowest. 9to1 and 1to9 are displayed as ‘GG’ and ‘FF’ respectively.

How accurate is the Performance Rating?

Extremely accurate. Metric is accuate enough to pass a blind test performed by a Grand Master player.

How is Performance Rating calculated?

Performance Rating is calculated by creating a variable out of every data and event that happens during a game that correlates to a player’s skill. We also include things like, how well you performed to a lvl3 gank, how much focus you attracted from the opponents jungler so your other teammates were risk free of a gank, how your ward placement revealed the opponents jungler and really almost anything you can think of. Stats such as kills, cs, damage dealt, level and gold are obviously included as well. It is also important to note that Performance Rating is calculated relative to a player’s position and tier.

Does it take factors that are not saved as data into consideration?

Everything is taken into account except voice and chat. A comprehensive evaluation of a player’s game could be accurately examined with the immense amount of game data that is available and we have fine tuned it to perfection.

Don’t you just get a high rating if your KDA is high?

Not at all. KDA is just one of the many variables we take into consideration.

How is Team Luck calculated?

Team Luck is calculated by taking the performance ratings of the player’s teammates and comparing it to the player and to the opponents team at the MMR at which the game was played.

This stuff only applies to low elo since there are things high elo players do that are not shown in the stats sheet. How does this work in high elo games?

The model we have developed works for any and all tiers. We are able to forecast end of season challenger SoloQ rankings based on previous performance ratings with a very low margin of error. We can even predict what tier you will finish the season at with extreme precision.

Where did this idea come from?

We wanted players to know how well they performed during their games to help players improve. We wanted to solve the player's pain of not knowing if and how much they were responsible for the outcome of a game.
