The rating of efficiency of a tank or its efficiency – one of complex indicators of game skill. It is considered at inclusion in top clans, in cyberteams, in companies. The calculation formula is quite difficult therefore players use different online calculators.
Calculation formula
One of the first calculation formulas looked so:
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 is given in the picture. In this formula there are following variables:
- R – fighting efficiency of the player;
- To – the average number of the destroyed tanks (the total number of frag divided into total number of fights):
- L – average level of a tank;
- S – the average number of the found tanks;
- Ddmg – average quantity of the caused loss for fight;
- Ddef – average quantity of points of protection of base;
- With – average quantity of points of occupation of base.
Value of the received digits:
- less than 600 – the bad player; about 6% of all players have such efficiency;
- from 600 to 900 – the player is lower than an average; 25% of all players have such efficiency;
- from 900 to 1200 – the average player; 43% of players have such efficiency;
- from 1200 and above – the strong player; such players about 25%;
- over 1800 – the unique player; such no more than 1%.
The American players use the formula WN6 looking so:
wn6= (1240 – 1040 / (MIN (TIER,6)) ^ 0.164) x FRAGS + DAMAGE x 530 / (184 x e ^ (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 a tank of the player if it more than 6, is used value 6
FRAGS – the average number of the destroyed tanks
TIER – the average level of tanks of the player
DAMAGE – an average loss in fight
MIN (DEF,2.2) – average quantity of the brought-down points of occupation of base if the value more than 2.2 is used by 2.2
WINRATE – the general percent of victories
Apparently, in this formula points of occupation of base are not considered, quantity of frag on the low-level equipment, percent of victories and influence of the initial zasvet affect rating not really strongly.
The Wargeiming company entered an indicator of personal rating of efficiency of the player which is calculated by more difficult formula considering all possible statistics in update.
How to increase efficiency
From a formula Kh (350-20khl) it is visible that the tank level is higher, the smaller quantity of points of efficiency turns out for destruction of tanks, but bigger for drawing a loss. Therefore, playing on the low-level equipment, try to take more frag. On high-level – to cause more loss (damag). The quantity of points of the received or brought down points of occupation of base affect rating slightly, and for the brought-down points of capture of efficiency glasses is charged more, than for the received points of occupation of base.
Therefore most of players improve the statistics, playing on tanks of the lowest levels, in a so-called sandbox. First, most of players at the lowest levels – the beginners who do not have skills, not using the pumped-over crew with skills, not using the additional equipment, not knowing advantages and shortcomings of any given tank.
Irrespective of on what equipment you play, try to force down as the bigger quantity of points of occupation of base is possible. Platoon fights strongly upgrade the rating of efficiency as players in a platoon act is coordinated and more often try to obtain a victory.
