I'm getting quite a few questions about changes to rating values, mostly in the form of "why have my ratings changed?"
The short answer is - ratings have changed because 0.8.6 did a big artillery reshuffle.
Basically, most of the high-tier arties got raised a level or two in 0.8.6, so for people who played these SPGs their average tier went up. And because all the ratings use average tier information (some directly, some less directly), the ratings change from that (most by quite small values).
I have already adjusted Performance Rating a bit to compensate for that (for example, I removed the "average tier adjustment" of +2 tiers for SPGs that was there). Still I will check later on if more tweaks are needed.
For WN7 and ER I don't control these formulas so I will wait until their creators decide to change them (or decide to leave them as they are).
But in any case - these changes apply consistently to everyone, and I retro-fitted them to previous snapshots to avoid any strange "ratings jumps", so hopefully they don't cause much disruption.
P.S. Also, the biggest confusion is for servers where 0.8.6 is not applied yet, so they will see their t8 arties as t10 arties already in NoobMeter. Hopefully they get 0.8.6 soon and all is well again.
P.P.S. Creators of ER rating have declared they will not adjust the ER formula, but will adjust the way it is interpreted.
I think the KD ratio is wrong.
ReplyDeleteIt looks like it's taking Kills divided by Survived, rather than Kills divided by Deaths.
Hmmm...
DeleteI checked on my account and it seems to match what I expect it to be ("destroyed / (battlesParticipated - battlesSurvived)").
I also checked the code and that is what it calculates and it uses the same formula as above.
Can you please provide examples using specific players where you think it is wrong?
Is the total K/D wrong, or just the "interval" ("recent") ones?
Looks like it's the interval, not the overall:
ReplyDeletehttp://i.imgur.com/5lkeHYy.png
81 kills
35 battles
19 survived battles (54.29%)
16 deaths
5.06 Kills to Deaths
8005 kills
5409 battles
1934 survived battles (35.77%)
3473 deaths
2.31 Kills to Deaths
It also seems like there are some rounding errors or something else weird...
ReplyDeleteHere's the whole thing:
http://i.imgur.com/zW6xNs8.png
For last 7 days
368 kills
201 battles
86 survived battles (42.79%)
115 deaths
3.2 kills to deaths
For 1000 battles
1742 kills
968 battles
383 survived battles (39.57%)
585 deaths
2.98 kills to deaths
As you can see, the KD is not quite right, but I am using the average kills and survived battles %s to back calculate what the kills and deaths would be... so maybe it's all just rounding errors. Maybe I am doing something wrong, but the overall matches!
Thanks for the examples. I think it is something rounding related.
DeleteBut in any case I rewrote the interval K/D rating calculation so hopefully it is more accurate now.
Hi, do you mind checking something for me? My Korean in-game ID '제이Jay' isn't working through the noobmeter website (comes up as 'check spelling). I also couldn't log in through the Korean Wargaming OpenID, which makes me assume something is wrong with the account and not my spelling. Thanks
ReplyDeleteI suspect Wargaming Korea has banned NoobMeter as a client :/. At least I get HTTP error 403 upon Korean requests.
DeleteI will try to restart the server with a different IP and see if that helps.
Hey, thanks a bunch! I've just searched my ID again and it seems to be working now.
DeleteThe server restart/different IP must have done it.
Thanks!!
No worries, thanks for reporting. The problem is that it could happen again. But let us hope not.
DeleteIt would be nice if on your profile page it would display any Top 30 lists your tank is on and a link to said list.
ReplyDeleteI like this suggestion, but there are some technical concerns I have about implementing it.
DeleteIt would be great if the ratings also considered if premium tanks/ shells were used.
ReplyDeleteThe performance of a player with regular shells destroying a tank with couple of hits is definitely better than somebody who 1 shotted the tank with premium shell.
Unfortunately WG does not provide this information.
DeleteOff topic: you know that noobmeter doesn't work without the "www" prefix, right? It's good practice to use only one main domain but the site should redirect to the proper setting on its own. I prefer the setting without the "www" with "www" acting as an redirect but it's up to you to decide. Either way - currently only the www.noobmeter.com works (and "new.noobmeter" whatever that is)
ReplyDeleteIt's probably just a misclick in the configuration of the domain and should be easy to solve.
Yes, good point, thanks for letting me know. Fixed now.
DeleteOff topic since I do not know where else to post this, but if we upload the wrong replay, how do we remove it? Thanks.
ReplyDeleteI will add this feature soonish.
DeleteI added a "hide replay" feature so no one else sees it (it doesn't remove it completely though) - let me know how it works for you.
DeleteHey, a bit offtopic - is it possible to delete replay you uploaded on noobmeter? I chosen wrong file and now i have really crappy replay uploaded.
ReplyDeleteI will add this feature soonish.
DeleteThank you - that will be great! Also thanks for all the good work you do!
DeleteTomasz, I added a "hide replay" feature so no one else sees it (it doesn't remove it completely though) - let me know how it works for you.
DeleteHi.
ReplyDeleteIs it normal that stats are not acurate up to date?
I have curently 9748 battles but your site still shows 9637.
Though i also can see only overal results and for last 1000+ battles....while if i check someone else i can see 7 days stats as well.
tnx
No, not normal at all - but what is your username and server, so I can investigate?
DeleteCan you change "105 leFH18B2" level fron 4 to 5? After 0.8.6 it is true. Thanx
ReplyDeleteChanged, thanks.
DeleteMy account not update last night.
ReplyDeleteSedziwoj
Pretty sure that is due to patch.
Delete... patch 8.7 which WG deployed, I mean.
DeleteHm, Grzybu has his stats, so... but maybe patch start meanwhile stats update.

ReplyDeleteNext problem,
ReplyDeletehttp://www.noobmeter.com/tank/eu/MT25
and this tank show in my last stats, but i dont have it in garage, so it must be some bug.
Sedziwoj
That is because WG changed all your old T-50-2 battles to be under MT-25, so for NoobMeter they seem just appeared (as it had no MT-25 battles for you before).
Deletegreat WG :D
DeleteIs the omission of the E-25 also a part of Wargamings API not returning certain tanks?
ReplyDeleteYes.
DeleteHello, 1 question about stats... about 1,5 month ago my account was resetted by WG for my request.
ReplyDeleteIn my stats are numbers from before reset eq. fights, tanks but there is new clan.
Stats are stable (nothing changed except clan) from date of reset.
Could you fix it?
I wrote this comment, becouse I can't find contact to you.
Thanks and BTW - good work.
My ingame nick - wi_tek.
I cleared your account, it should reread it now (still cached so in a few hours).
Deletethanks a lot :)
DeleteHi!
ReplyDeleteMy battles in the T-34-3 are not showing up.
User Captain_Hindsight (EU)
Thanks!
Hi,
ReplyDeletehow can I remove my replay?
Regards
You can hide it. Then only you can see it.
DeleteHow can I hide? I do not see any option to do this.
DeleteYou have to be logged in using same WG user account as made the replay.
DeleteI am logged into my account, but I cannot locate this option :(
DeleteCan you remove the replay from my account?
Send me the link.

ReplyDeleteSorry to request a support question here, but our clan changed its name a while back from LIA to FENRIR (FNRIR in WOT), can you reset it so that if someone searches for FENRIR on Noobmeter they can find us?
ReplyDeleteLIA = OLD (Nov-2013) Gone
FNRIR = NEW

I beg to correct statistics on these tanks I went out for a long time (this is seen count fights)
Pz.Kpfw. IV Ausf. H
Pz.Kpfw. III
I think there is something wrong with my stats (rumburak3 EU server). Column "last 1000 battles" shows adverse WN8 - while all the other parameters - comparing to other column are on equal/higher levels (performance/efficiency/WN7, damage etc). Could you please re-check it?
ReplyDeleteMy stats have become somewhat confused since the 9.3 update (OzzyOnTap)
ReplyDeletethe second time I statistics are falling even as I do not play lost nearly 150 points. and every day I was ahead. why
