I was just thrilled to be on the high side of average.

I didnt even know what the hell a unicum was until someone in my clan started calling me that one day, who made up that word?


And for the record I believe I am just an average player with situational awareness.

I love this number because it has kept me from getting REALLY frustrated with some tanks, and it helps to keep win/loss record in perspective.  I am a player that loves playing new tanks, and I have played 96 of them, so it took me forever to save up the money to buy my Ferdie and Tiger II.  I finally broke down and sold a few of my favorites, Jagdpanther, KV-3, KV-1s, etc, and I bought the Tiger II and Ferdie on the same day.

I had never been so disappointed in a tank as I was with the Ferdie.  In 1700+ battles in TDs I thought that I would kick ass in the Ferdie, but my win/loss started around 20% and stayed low battle after battle.  Looking at the Efficiency rating I was performing OK though (12-1300), so it kept me willing to work through the grind to get the better guns.  Now with 43 battles I have clawed my way up to 42%w 56%l and 2%d with a 1588 efficiency, and I still have 7k exp to go to unlock the top gun and 38k exp to unlock the best engine.

Logically I know that with an 80% hit ratio, an average damage dealt of 1419 per battle, and an average of 1 medal every 5 games I am doing pretty good, but sitting at such a horrible win ratio when I am in the top 1/3 of most battles makes it hard to want to keep playing a tank that I could sell for nearly 2 million credits.  The Efficiency Rating has become my new number of choice because it lets me look at my actual performance, and helps me remember that sometimes luck DOES play a huge role in early win ratios.

On the flip side, I have a 56% win rate with my EZ-8 in around 75 games, but never felt that I was all that great with it (I am horrible with pretty much every American tank, much to my dismay).  My Efficiency rating of 925 shows me that my teams were winning despite me, not because of me :), and that selling it off was a good idea.

I know that this rating, like every other one, is not perfect, but since it takes multiple factors into account instead of just looking at one number, it sure seems like the best gauge we have so far.

I barely qualify as an average tanker  :(  Reasonably accurate, I'm smart when I think things through but I realize I'm not a particularly talented tank commander.  AND I'm overly aggressive  :D

Though I think I rate higher in the average subset since there are some intangibles that the calculator can't take into account...like how 85% of the time I'm filling massive voids in the line (read: entire flanks) and, as a result get overrun when 3 tanks of similar tiers to myself (or higher) show up to blow my turret out the exhaust.

Personally i'd say you are giving this efficiency calculator too much importance. What that tells you is that in those game you won 56% of those games with an efficiency of 925. Sure, play and try to improve that efficiency, but don't assume that because that efficiency is lower than some other tank that you are therefore not holding your weight. Remember that the calculator strongly favours heavies - whether it's by the games +45% or not is unclear. But given that's your weighting in game, i'd equate that 925 efficiency to something more like 1300 of a heavy.

My suggestion would be to keep tabs on your win% - and use the efficiency as one of the means to improving that win%. In other words, if you won 56% with an efficiency of 925, you'd probably win even more with an efficiency higher than that.

If you have situational awareness then you ain't an average player!  An average player doesn't even notice when the home base is being capped!

Win % already takes everything you can do to win into account. The calculator simply picks four things and turns them into one number. For a start you're measuring based on less data. Then theres the fact that the four stats it does look at are weighted according to whatever biases the creator of the algorithm has.

I would be extremely suprised if the creator actually analysed the full body of stats across the community and then determined what the weights should be. Same goes for the tier weights. Did they creator look at the average in each tier and weight based on that? I doubt that.

On topic: I don't judge you for using statistics any way you want and I'm very astonished to get neg for sticking close to the requirements of a quoted law. Just goes to show how much common sense is worth here.

There are several ways you can create and use statistics and that's what this fuss is all about. The way WG set stats up is more likely geared towards the information they want to gain, not you.

And above all things, there is a scientific way to handle statistics. As I tried to point out already: stick to the definition of the law and work with it. That is the correct and proven method. Doing it any other way, just to save time or because it's more convenient is just asking for trouble.

Ultimately only WG knows what these statistics truly represent, assuming they did their homework right. The best you have right now are guesses and wishes. Don't put too much weight on statistics that are not properly documented. That's just asking for trouble, believe it or not.

That is bad players. They dont know the base is being capped. The average players only know their base being capped when the red bar popped up. The good players predict the inevitable base capping and already in position to defend the base.

Get the win rate mod and spectate the high win rate player. You can see their position, target priority, and movements are totally different to those with 45% or less.

Everytime i spectate someone, I can tell right away if he got less than 45% winrate.

i love outperforming other players though when im in an "inferior" tank. im not talking tier wise im talking t34 fighting is-4, apparently the worst t9 heavy fighting one i believe to be of the best, or the best. but anyways on to the story

i was on lakeville in my t34, top tier, only other t9 was an is-4. i decided to go city because its closer together and i excel in close quarters. so anyways i go and the first thing i spot is a type and one shot later hes running like a scalded cat. litterally. so i advance cautiously up the city trying to find my next target, and i start overlooking via a hill on the same type, i fire and do about 300 damage to him again. then i get shot from behind and my ammo rack gets hit, so i turn right around to see an is-4 staring me in my face. i click the rep kit as fast as possible onto the ammo rack and proceed to fire smack dab into the middle of the is-4s armor, doing about 400 damage to him ( all i could tell is that he has the upgraded turret from the 1790 hp) and of course causing him to back right around the corner. i figured out i reloaded faster then he did when he came back round the corner just as i reloaded, and popped another shell into him while he returned the favor, both penning i think. i go and fire at him again since he is retreating then wait a while since im at 470 or so hp and hes 1 shot away from death, asking my allies who have succesfully taken the lower city to assist me, they didnt. so i rounded the corner and he popped out and we both dinked each other, with me falling back cause of my armor on the hull is easy to pen. after a while since noone was helping me i decided that since the valley was lost, i might as well bring him down with me and i rounded the corner one last time and he lit up like a christmas tree, coming around the corner from a hill to pop me first, he didnt. without aiming i managed to hit his side, killing him in the process and winning the duel. unfortunately we did not win the battle as they had succesfully taken the valley a while ago and took over our base as i was about 50% done with capping theirs. sad tragedy but i impressed myself during the duel, managing to kill an is-4 from 100% hp with him getting the first shot in the process ;) with the 120mm of course. later in himmelsdorf today i figured out you can pen an is-4s top turret via a little spot on its turret, right on the front as well. i gave one a nasty surprise when i did 500 damage to him by that weakspot lol

If you are a dedicated scout IE T-50.
Destroyed,damage,defense and capture averages are low and really don't attest to your abilities.

And realistically neither does 'spotted'. If only there was a stat for damage done by others while spotted by you.

The Efficiency Rating Calculator should maybe calculate each tank you used individually.
I suck with the meds but I am above average in the T-50.

The dossier tool does exactly that and gives you a lot more data as well.  The efficiency calc is the same - the bottom line overall score is the same as given by the efficiency calculator.

Dossier tool is here:  http://wot-dossier.appspot.com

The dossier tool does individual calcs for you. Tends to highlight how skewed efficiency as a rating tool is. If you are winning it matters little what your efficiency is. And conversely if you are losing with a high efficiency you clearly aren't doing something right.

You can always share it. Just post the link http://wot-dossier.a.../dossier/xxxxxx and people will be able to get stuck right into your tasty stats.

I have to agree with this - there isn't a stat to see this info, except maybe xp earned.  But if a scout is good an can light up a lot of enemy tanks while team-mates damage & destroy them, that scout will earn a LOT of credits & xp and is a good scout.

This is from that sort of play:

It isn't every day you earn over 56k profit from a non-premium tier 4 tank that only fired 1 shot during the entire battle.
There was a 2nd scout that died within the first minute or 2, if that scout had rushed into the base spotting all the enemy first then I would not have gotten the detects for 'scout' but I would have still earned a LOT!
