Overall picture

O-I Experimental 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.

Marks of Excellence

Lower is better

The bar shows the combined damage required for each mark of excellence. All six bars share one scale — the shorter one marks the vehicle on which the mark is easier to earn.

Standing within the tier

Percentile among all vehicles of the same tier

Both vehicles are measured against their own tier, not against each other. That keeps a cross-tier comparison readable: the percentage states which share of the vehicle’s own tier scores worse.

The advantage is highlighted in the colour of its side — for the MoE thresholds that is the lower value. Expected values are reference figures for the WN8 calculation, not vehicle statistics: they state what an average player achieves in this tank.
