The efficiency rating of a tank or its efficiency is one of the complex indicators of playing skill. It is taken into account when admitted to top clans, cybersport teams, and companies. The calculation formula is rather complicated, so players use various online calculators.
Calculation formula
One of the first calculation formulas looked like this:
R = K x (350 - 20 x L) + Ddmg x (0, 2 + 1, 5 / L) + S x 200 + Ddef x 150 + C x 150
The formula itself is shown in the picture. This formula contains the following variables:
- R - player's combat effectiveness;
- K - the average number of destroyed tanks (the total number of frags divided by the total number of battles):
- L - medium level of the tank;
- S is the average number of detected tanks;
- Ddmg - average amount of damage done per battle;
- Ddef - average number of base defense points;
- С - the average number of points of base capture.
The meaning of the digits received:
- less than 600 - a bad player; about 6% of all players have such an efficiency;
- from 600 to 900 - the player is below average; 25% of all players have such an efficiency;
- from 900 to 1200 - the average player; 43% of players have this efficiency;
- from 1200 and above - a strong player; there are about 25% of such players;
- over 1800 - a unique player; such no more than 1%.
American players use their WN6 formula, which looks like this:
wn6 = (1240 - 1040 / (MIN (TIER, 6)) ^ 0.164) x FRAGS + DAMAGE x 530 / (184 xe ^ (0.24 x TIER) + 130) + SPOT x 125 + MIN (DEF, 2.2) x 100 + ((185 / (0.17+ e ^ ((WINRATE - 35) x 0.134))) - 500) x 0.45 + (6-MIN (TIER, 6)) x 60
In this formula:
MIN (TIER, 6) - the average level of the player's tank, if it is more than 6, the value 6 is used
FRAGS - average number of destroyed tanks
TIER - the average level of the player's tanks
DAMAGE - average damage in battle
MIN (DEF, 2, 2) - the average number of knocked down base capture points, if the value is greater than 2, 2 is used 2, 2
WINRATE - Overall Win Rate
As you can see, this formula does not take into account the capture points of the base, the number of frags on low-level vehicles, the percentage of victories and the influence of the initial exposure on the rating do not have a very strong effect.
Wargeiming has introduced in the update a player's personal performance rating, which is calculated using a more complex formula that takes into account all possible statistical indicators.
How to improve efficiency
From the formula Kx (350-20xL), it can be seen that the higher the level of the tank, the less efficiency points are obtained for destroying tanks, but more for causing damage. Therefore, when playing on low-level vehicles, try to take more frags. At high-level - to deal more damage (damage). The number of points received or knocked down base capture points does not significantly affect the rating, and for the knocked down capture points, efficiency points are awarded more than for the received base capture points.
Therefore, most players improve their stats by playing on lower tier tanks, in the so-called sandbox. Firstly, most of the players at the lower levels are beginners who do not have skills, do not use a pumped-up crew with skills and abilities, do not use additional equipment, do not know the advantages and disadvantages of one or another tank.
Regardless of which vehicle you play, try to shoot down as many points of capture of the base as possible. Platoon Battles greatly increase your Efficiency Rating, as players in a platoon act in a coordinated manner and more often achieve victory.
