Overall picture

FV4201 Chieftain Proto leads in 5 of 7 comparable metrics.

Only mutually independent values are counted: win rate, average WN8 and the five expected values. Battle count measures popularity rather than strength, and the MoE thresholds are arithmetically the same figure as average damage — both stay out.

Strength profile

Five axes side by side

Each axis is scaled to the range of the tiers involved: the outer edge is the best value of the tier, the centre the weakest. The shape therefore shows where a vehicle stands among its peers — not merely which of the two numbers is larger.

Standing within the tier

Percentile among all vehicles of the same tier
