Source: http://forum.worldoftanks.ru/index.php?/topic/995453- New 8.8 personal rating is a complex index of player’s combat efficiency, based on six parameters: - average experience (without PA bonus) - average damage dealt per battle - amount of battles played - winrate - winrate in battles where the player survived - hit rate In order to make the rating system more fair, average experience per battle will be calculated freshly from the point of 8.8 going live (new system introduction). Player experience, gained before 8.8, will not be taken into account. The new system has following advantages: - more objectivity: only pure XP gained will be taken into account, without PA or event/special bonuses - not only player’s skill, but also player’s experience (archieved by the amount of battles) will be taken into account - new accounts opened only for statpadding/twinking will never have good rating, because they will have low battle amount. This urges players to develop their main account and helps to fight twinks/sealclubbers/pedobears - the rating is based on internal WG data, which guarantees the rating accuracy and makes it impossible to “fix” it (the way 3rd party can) The rating formula is as follows: bc – “BattlesCount” (amount of battles played) win – winrate (a number from 0-1 interval: 55 percent equals to 0,55) surv – winrate in battles you survived (a number from 0-1 interval) hit – hitrate (0-1 interval) xp – average experience dmg – average damage dealt More accurate formula will be introduced in 8.9, it will take into account the changes coming in 8.9
