The Calculated Playing Levels of GTN

​Every match you play and record on GTN, whether it be a practice, ladder, tournament or league match, gets used to calculate your singles or doubles playing level. This helps you accurately assess your playing levels, and also find opponents with a similar playing level.

Playing Level Badges

On every profile page, you can see a player's playing level badges. These badges give a quick reference to a player's calculated singles and doubles playing levels. The badges include:

- The accuracy of the calculated playing level. The more unique opponent matches played, the better the accuracy of the calculation.
- The calculated playing level from 2.0 - 6.0. Where 2.0 is a beginner, and 6.0 is semi-pro.
- A historical graph representation of calculated levels over time.

The Algorithm

To calculate your playing levels, we use a complex algorithm loosely based on the Elo System. The Elo System is a well know ranking system used by many organizations to rank players or teams. 

Calculated playing levels are calculated each night at midnight (PST). For each match played, the system takes into account your opponent's playing level, and the accuracy of their level. The more accurate your opponent's playing level, the greater the influence it will have on your own. The lower your playing level accuracy is, the more it can fluctuate. The higher your playing level accuracy is, the more stable it becomes.

Calculated Playing Level Chart

Over time, your playing level will change. You can even track the changes directly on your profile page.

As you improve, you can watch as your levels increase. And as you play more matches, you can watch the "accuracy" increasing as well.
