Efficiency rating dropping like a stone

[ghost-guns 1,486]

My efficiency rating has gone down 20 points over the last month but I have done nothing different. Winning most battles, finishing in the top places with a positive k/d. I earn more crystals than experience points. What gives? The only thing I don't do is play DM, seige or juggernaut.

I think supplies affects efficiency - do same thing with less supplies and your efficiency should be better.

Using drones more?  (batteries are supplies)

[cosmic666 1,055]

a good efficiency rating depends on xp to crystals. The more xp you have to crystals the better your rating. its not easy but double battle funds does help.i dont think supplies has a effect on rating. the more xp and the less crystals per xp seems to boost your ratings. i could be wrong but this is what i have observed with a lower account (general).

It could just be that other people became more "efficient" than you and pushed you down.

[cosmic666 1,055]

yes could be that to. no one knows how ratings are worked out so we all just guess at how it might be done.

any ideas how it is done?

Not sure exactly, but it seems to depend on factors like hours spent in-game, average position in battle score tables, K/D, use of supplies, total amount and upgrades of garage equipment, maybe also something like EXP/hour rates.

And does efficiency rating change after every weak? I know it doesn't reset to 0 like 'gold boxes caught', 'experience earned ', etc every week. So when do the values of efficiency rating change?

Efficiency ranking is gradual (i.e. static) and is not reset on a weekly basis, unlike all of the other rating types.

All of the rating types are being automatically updated on every few minutes; including Efficiency rating.

In the last Jugger solo event i boosted my acc 500 points playing just that event, but when i play normal MM in wich most of time have the same wins and losses becomes really hard to keep increasing my rating. What i see is that the crystals per XP your earn is a important fact. In that event i was 6.3 crystals per 1XP cause of the increased battle funds obvs. I checked my rating during event many times and it was increasing really fast. And now with the 2x lockdown funds i just get 2.5crys per 1XP and as i say my rating hardly increase or even i decrease. So try making a good work during next special event and u will increase it, i promise. This maked me understand why the are no solo modes i MM.

Efficiency rating is just another useless stat. Mines like 20k points worse than yours, but I don't let that affect me.

its something to aim for for some players at the lower ranks for when they do reach legend.

I think it updates at the same time as all the other cumulative stats, like total kills, overall K/D, hours played, etc. About once an hour, maybe less often.

[Asvoria 37]

The dominant factor the determines the efficiency is the crystals to experience ratio. So try to earn less experience and earn more crystals. Normally this is done by doing objectives in a match like capture the flag, capture the point, etc and at the same time make less kills since it gives the most exp and you don’t want that. The best time to increase efficiency is during 2x funds. So this is all you really need to know about how efficiency is earned though I really see no point in it since the top players are all mults.

[von_Cronberg 258]

The efficiency rating is a formula based on overall crystal rewards earned divided by overall experience earned, possibly with a small role for the overall k/d ratio. This is pretty obvious, as the efficiency rating is equally calculated for players who never played a battle after the statistics expansion that came with the implementation of public account profiles, and before that expansion, the account data collected by Tanki was limited to the aforementioned information. The formula thus can only draw on this limited information for input.

Whenever Tanki introduces "special" periods of earned experience increased by a certain factor, like it recently did during the Corona lockdown campaigns, the efficiency ratio of every active player drops visibly, as increasing the crystal rewards by the same factor apparently is not enough for the efficiency rating formula.

On the other hand, "special" periods of keeping the experience earned as usual but increasing the crystal rewards by some factor, that boosts the efficiency rating of every active player considerably. As does playing with Premium, which increases experience earned by a factor of 1.5 and crystal rewards by a factor of 2.

Or it's not quite that simple....

"Efficiency/Effectiveness Rating - this is calculated using a complicated formula which reflects how effective you are in battles. There is a separate section which shows the Top 100 players efficiency-wise. This ranking is gradual and is not reset weekly. Please note that the formula used to calculate efficiency/effectiveness has not been disclosed by Developers."

[DaringDeer 656]

While no one knows the exact formula, there are three main factors in the calculations.  Up until Legend 1 rank, you get a large boost each time you rank.  After that, the strongest correlation is with crystals to experience ratio (C/E).  Third is K/D ratio.  There are definitely some other, lesser factors involved. 

The recent experience bonuses hurt your C/E.  If you are concerned with efficiency, you shouldn't play during the time with experience bonuses.

People that are able to be juggernaut because of connection speed to servers are able to take advantage of those modes and gain high K/D.  Solo juggernaut has been the key mode used for players to achieve high efficiency.  Many people on the top 100 list only play their account during special events with Solo JGR or during crystal multiplier events (without experience multipliers of course).

A lot (not all) of the high efficiency players game the system to artificially increase their efficiency.  For example, using mechanic drone gives you score and consequently crystals but no experience.  Dictator overdrive does the same thing.  Many people exploited this during the time period when the scores given for those were higher.

Another way it is gamed is via pro battles.  Imagine a semi-private battle.  The account trying to boost C/E makes no or minimal score but all other players leave before end of battle to give all crystals to this account with very little corresponding experience. 

I'm sure there are other ways to game the system.  For a time I tried to get in top 100 but could never crack 115 playing straight up.  I do know several of the top players like Kepa and Anything and they are just damn excellent players.

Sheet of stats for most of top 200:

https://docs.google.com/spreadsheets/d/e/2PACX-1vRfqniDPRd0hTEnKjXFQFw6Gp62cRL7ZWIegMkw693SRGPY8vd5cJdwdVxlV8NiHrUA790RlYoawiVd/pubhtml?gid=0&single=true

Below are some screenshots from my stats tracking app for myself, Yarik (mainly very good player but some exploitation), and Cat (lots of exploitation).  C/E for a good player is going to be between 2 and 3.  I've never had a daily C/E over 5.  If you see a C/E for a day that is over 7 you know the player is gaming the system.  In the screenshots, the numbers to the right of C/E and K/D are the daily numbers.  Red if lower than overall and blue if higher.  If you look at mine you can see exactly when the efficiency bonus has been in place.

Incidentally, I expect the Closing account to take over #1 spot once it ranks to Legend.  I've never seen another non-Legend account in top 100 and his C/E and K/D is better than Yarik's.  (I don't have any stats for this account because it hasn't been played since I added him to tracking.)  My guess is it will rank during birthday celebration if experience bonus is not in play.

I met Cat in battle several times. I wish to testify that he/she is an excellent player, too.

yip i got told that the top player once got over 3000cry for like 10 xp dont no how he managed that but he did seems impossible if you ask me

[DaringDeer 656]

@von_Cronberg Agreed, I have as well.  You don't get to top 100 without being an excellent player.  Some just do things to manipulate the rankings beyond their skill.  Playing only during high crystal events is certainly the most common tactic.

Meant to include Yrap_cool stats too.

exploitation do you mean cheating if so use the word cheat if not explain what the word refers to.

@DaringDeer 

I use the opportunity to generally appreciate your enormous statistical efforts around this game. I do not least remember this forum comment of yours, a detailed snapshot of equipment used among active high ranked legends, as most interesting. You should make a regularly updated thread on this, I would find it more readworthy than anything else in this forum ...

agree with the BEING A GOOD PLAYER but there are those that do so unfairly and basically cheat to reach top 100. And yet they still get praise off players which only boosts there already inflated ego beyond there actual skill level.

[cosmic666 1,055]

AbsoluteZero  is the one to ask about stats he has detailed graphs on most of these players. sadly he left the game and im not sure if he kept up with the stats are not.

I am aware of some dozens of players which I know from repeatedly meeting them in battle and who just display extraordinary skill and performance in playing this game. I do not think there is anything wrong with these players getting an ego boost from their extraordinary skill and performance.

What I'd rather have an issue with, that is players who lack outstanding skill but nevertheless seek unwarranted boosts for their ego. And the number of those is by many orders of magnitude higher. Piercing the empty balloon of the ego of those is magnificent entertainment in this game.
