These are two calculated "chances" of winning, using slightly different forumlae.
- K is the more basic of the two, looking only at the efficiency rating and tier.
- M takes more variables into account, such as number of battles and previous winrates.
For M, the forumla is:
E=efficiency of player
R=GWR of player
B=normalized number of battles of player (number of battles divided by 100000)
Tmin=min battle tier of current tank
Tmax=max battle tier of current tank
M=effectiveness of player calculated by efficienecy, winrate, battles played and tier
Kc=sum of calculated M for all allies
Kn=sum of calculated M for all enemies
K= win rate
For K, the formula is:
Esi allied player efficiencies
Usi allied player tier (Epi Upi being enemy stats)
