Hát, sajnos csak azt tudom hozzátenni, hogy elvileg így számolódik:
Step 1 takes the counts of tanks played on account, and multiplies them by the expected stats to get the account total expected values. Then the actual account totals (your total dmg, frags, spots, def, win-rate) are divided by the total expected values to give the ratios.
rDAMAGE = avgDmg / expDmg
rSPOT = avgSpot / expSpot
rFRAG = avgFrag / expFrag
rDEF = avgDef / expDef
rWIN = avgWinRate / expWinRate
Step 2 sets the zero point for the ratios. See the assumptions section for more info on why this happen. min and max are functions to ensure the ratios stay within bounds. The constants are in the format of
rWINc = max(0, (rWIN - 0.71) / (1 - 0.71) )
rDAMAGEc = max(0, (rDAMAGE - 0.22) / (1 - 0.22) )
rFRAGc = max(0, min(rDAMAGEc + 0.2, (rFRAG - 0.12) / (1 - 0.12)))
rSPOTc = max(0, min(rDAMAGEc + 0.1, (rSPOT - 0.38) / (1 - 0.38)))
rDEFc = max(0, min(rDAMAGEc + 0.1, (rDEF - 0.10) / (1 - 0.10)))
To normalize that, a player with all rSTATSc = 1 would receive 1565 WN8. A player with all rSTATS = 1 would also have all rSTATSc = 1 because (1-c)/(1-c) = 1.
(rSTAT – constant) / (1 – constant)
Step 3 takes the weighted (in Step 1) and normalized (in step 2) performance ratios and processes them through the coefficients determined for the final formula, reported above. This puts the scale on the more meaningful 0-5000, gives the relative weights of damage and reflects the interactions between frags*spots, def*frags and dmg*frags.
WN8 = 980*rDAMAGEc + 210*rDAMAGEc*rFRAGc + 155*rFRAGc*rSPOTc + 75*rDEFc*rFRAGc + 145*MIN(1.8,rWINc)
