World of Tanks Marks of Excellence: How the Percentage Works and How Many Battles You Need

Marks of excellence (MoE, gun marks) are the stripes on a tank's barrel that show how your damage on that tank compares with everyone else who plays it on your server. One mark means you beat 65% of them, three marks put you in the top 5%.

The rules fit in four lines. What most guides skip is the math behind the percentage — and that math explains why the third mark takes so long, why one bad battle hurts so much, and why your number can drop on a day you didn't play at all.

How the MoE Percentage Is Calculated

After every Random Battle the game takes your combined damage: the damage you dealt plus the largest of three kinds of assisted damage — spotting, tracking and, for SPGs, stun. Only the largest one counts; they don't add up. A light tank that spots for 3,000 and tracks for 1,500 gets 3,000, not 4,500. Damage you blocked with armor counts for nothing.

That number goes into a moving average kept for this tank only. Wargaming describes it as "your last 100 battles", but old battles are not cut off at 100: the average behaves like an exponential moving average in which each new battle has a weight of about 2% and older ones fade gradually.

Once a day the game recalculates, separately for each tank and each server, what combined damage players reached over the past 14 days. Your moving average is placed on that distribution, and the result is the percentage you see after a battle.

What doesn't count: Frontline, Onslaught, Steel Hunter and other special modes, training rooms, wins and losses, experience, and blocked damage. A won battle with 1,200 damage is worse for your marks than a lost one with 4,000.

Why Your Percentage Moves the Way It Does

It is a rank, not a share of the required damage

90% doesn't mean you have 90% of the damage needed for three marks. It means your average beats 90% of players on this tank. On most tanks the top of the distribution is thin, so the damage gap between 85% and 95% is usually wider than the gap between 65% and 85%. That's why the last 10% feels slower than everything before it.

It can drop on a day you didn't play

The bar comes from other players' last 14 days and is recalculated daily. After a buff, a popular event or a wave of strong players picking the tank, the same moving average can sit lower on the scale the next morning.

One great battle helps less than you think

With a weight of about 2% per battle, a 7,000-damage game on a 4,000 average lifts the average by only about 59. Marks come from a run of good battles, not from one highlight.

How Many Battles a Mark Really Takes

Because the average is weighted, the number of battles depends on two things: how far your moving average is from the bar, and how far above the bar you play in each battle. Playing exactly at the bar never gets you there — the average only creeps closer.

Example: the three-mark bar on your tank is 4,000 combined damage, and your moving average is 3,600.

Your own numbers. Battles ≈ ln((S − A) ÷ (S − T)) ÷ 0.02, where A is your current moving average, T is the bar for the mark and S is what you expect to average per battle. The bar for your tank and server is shown on community trackers such as Tomato.gg; MoE mods from the official wgmods.net show your current moving average.

The estimate assumes a steady average and a bar that doesn't move. Real battles swing, and the bar shifts daily, so treat the result as the order of magnitude: 35 battles and 110 battles are different plans.

What One Bad Battle Costs

Close to the bar, losses hurt more than gains help. With a moving average of 3,950 and a 4,000 bar:

That changes how a mark session should be played:

• Don't trade survival for one more shot early. A zero-damage death costs about as much as eight strong battles bring back.
• Stop after two weak battles in a row. Tilt is the most expensive thing in a mark grind.
• Play the mark tank only when you can focus. Warm up on another tank; the moving average doesn't care that you were tired.

Choosing a Tank Worth Marking

The tank you pick changes the effort as much as skill does, because the bar is set by the people who play that tank:

• Check the bar for your server first. Two tanks of the same tier and class can need very different damage.
• Tanks popular with strong players have high bars. A meta tank attracts players who already average a lot on it.
• Pick consistency over peak damage. Good DPM, gun handling and a playstyle you can repeat every game beat high alpha you can't use safely.
• Get the setup ready before you start. A fully trained crew and the right equipment; every percent of gun handling turns into damage.

Different Classes, Different Routes to the Same Number

How Long a Third Mark Took on Real Orders

Most of the spread comes from where each tank started: a tank already close to 95% needs a dozen strong games, a long climb needs hundreds. That's the same math as above — and why an honest estimate always starts with your current percentage.
