NoobMeter blog: Patch 8.3 / January tank winrates and OP Rating

I ran a report on my local, large NoobMeter.com database looking at what results people have had in 8.3 and found it quite interesting.

How is this report different from the many others on other sites? Well, I also included Player winrate (WR) for players which own a particular tank in the data, and also calculate a rating called "OP rating" which compares Tank WR with Player WR.

As you can see from the results, the new tanks are generally first played by the most skilled players. If one blindly evaluates new tanks using their WR, that can lead to incorrect conclusions. For example, just because tank X has 52% WR while other tanks in that category have 50% doesn't mean it is OP - perhaps it is simply played by players who on average have 54% WR, and is thus in fact under-performing!

This is why this report provides a more accurate picture.

The report was run on the EU server data between 17th of January to 27th of January, but the conclusions should carry over to other servers.

Explanation of the columns:

Tank WR - victories / battles in percent for this particular tank
Player WR - victories / battles in percent for players playing this tank
OP Rating - Tank WR / Player WR - the higher the more OP

Note that I don't really have all the battles/players represented (I'm missing some low-battle players) - this is why the Tank WR for low-tier tanks are larger than Player WR for these tanks. The sample set isn't 100% representative of the server population, it has the NoobMeter.com users slightly over-represented, and they are generally above average players. I plan to get a more representative set for the next report.

The t10 tanks all have poor OP ratings, I think that is because they are owned by the best players (good Player WR ratings), who can crush the low-tier random games against less experienced players, but then when playing t10 tanks they meet other good players - whether in CW, TC or even randoms, and thus no longer win that much.

The poor showing for 121 and FV4202 could be due to low sample sizes, but it seems that M48A1 has been nerfed too much. It can also be seen that it is no longer played much by the players.

AMX 50 Foch 155 is ridiculously OP, the JagdPz E-100 clearly struggles, while the o263 has a small sample size.

The T54E1 seems quite OP. T-54 is doing, possibly due to the best players playing it with HEAT where it is very much OP. The Patton and especially Lorraine 40t can be seen as nerfed too much.

IS-6 and KV-5 performing very well, I think the gold ammo for credits has helped them as they lacked good guns. FCM 50t and VK4502A are both underperforming.

Here we also clearly see that M6A2E1 is owned by the best players - as it was a pre-order special so mostly players from the beta times got it.

While this is very interesting, I think it would be even more revealing if you could calculate OP rating on a per-player basis. That is, instead of dividing overall Tank WR by mean Player WR of players owning said tank, divide individual Tank WR by individual Player WR. You could then use a weighted average (based on number of battles in the tank) for the overall OP rating. You could also then stratify by Player WR. It would be interesting if there are certain skill magnifying or compressing tanks that particularly powerful in the hands of the better players while being extremely weak in the hands of worse players (I imagine this is true for many high tier FR tanks, for example).

Alex, thanks for your comment.

It is a very good suggestion, although I'm not sure it will result in much different results as the Tank WR and Player WR I use is already a weighted average by the battles in the reporting period (that is, I'm not taking the Tank WR and then calculating the mean for that, instead I'm summing all the victories and all the battles for that tank, and only calculating the (victories/battles) as the last step).

The main difference, if I see it right, is that in your suggested approach Player WR would be weighted by the # of battles players have played in the particular tank being evaluated, as opposed to the total # battles in the reporting period.

I will see if I can implement it for the next report.

The point that some tanks are likely disproportionately OP for best players and disproportionately UP for worst players is also very valid, and the suggestion of proving that by stratifying by Player WR is a great idea too.
NoobMeter30 January 2013 at 03:29
By the way, assuming I do end up stratifying by Player WR, any suggestions how to easily make this data presentable? As posting 3 different sets of tables for, say, below average, average, and above average players seems quite ineffective (the report as is takes up a lot of space). I guess I could introduce more columns ("OP rating for players w/ WR 52%+")... just thinking maybe there is some more elegant solution.
Anonymous30 January 2013 at 16:49
Okay, I see what you're saying. I wasn't quite sure how it was calculated from the initial write-up. For the stratification, I think it depends. Personally, I think it would be most interesting for Tier 8+, which definitely limits the number of tanks one needs to consider. Lower tiers (particularly below 5) are pretty chaotic. I'm not sure what the best stratification would be. Maybe just quartiles? Or maybe the tails are the most interesting, so something like the bottom 10%, 11-50%, 51-90%, top 10% (of winrates).
NoobMeter31 January 2013 at 06:53
Okay, I ran such a report, dividing by WR < 46% "good", WR 46%..50% "avg", WR > 50% "bad" and then compared the respective "OP ratings" for the good vs bad group. The problem with using the tails is that we run into too small sample sizes more often.

Some of the top results were due to insufficient sample size, then came stuff like "SU-122-54", Centurion Mk1, IS-4 (!?), 110, M6A2E1, KV-1S, SU-26, T110. So these would be the tanks where the best players outperform the worst players more than usual.

Very strange results, I expected the French tanks to be at the top of that list.

At the bottom of the "good / bad OP ratings" list is stuff like Lorraine 155 51, M22 Locust, AMX38 and other mostly low-tier tanks and arty. Perhaps that means these tanks don't influence the game much therefore the best players cannot win the games for others in them and the worst cannot lose the games for others by taking them.

I'll think if I can make this presentable, but overall the results are strange enough that I'm not sure there is much value to publishing them. I can upload a 170 MB CSV file with data about battles during the last few weeks if anyone wants to play with it. Or the resulting ~260 row file w/ row for each tank.

Awesome data collection and editing!

Some remarks to two tanks:
IS-2, my OP rating: 1,25
110, my OP rating: 1,18

These two tanks are hillariously overperformant at the moment.

Now about another tank:
I switched to the WZ-111 1-4 ... I MY GOD!
Compared to the 110
- my average damage went down from 1950 to 1450
- my damageration dropped from 1,6 to 0,9
- my average exp dropped from 1050 to 770

But suprisingly the vitory ration is at 61,3%, so still OP by 1,04 for me. Mybe I get the "everybody wants to kill me because I'm so rare" bonus

The thing that immediately caught my attention is the massive win% inflation that players engage in. If players had "honest" stats, I would expect Tier X win% to be better than overall win% as the tanks are always top tier in every battle. However, looking at the results, it seems all tier X tanks perform 3-4% below overall. Normally I come down hard on the "stats mean things" side of an argument, but this data looks terrible for win%. Have you thought of doing an OP rating using efficiency/WN7/performance rating?
