You're looking at a super small sample size of 150 games here, which is not conclusive data at all. The data from these small numbers of games swings wildly. For example 3v3 top 200 with 277 games from 16-06 to 18-07 shows the complete opposite with Allies on 60-64% wr. The data only starts being reliable at sample sizes of like 3000-5000 games minimum.


No, it was 568 games for that time period. Also, if you want a good measure of the variability of data, you can take a bunch of individual samples and get an estimate of how many you would need for statistical significance. It isn't just some set number like 3000. I did a small portion of that, just as a reality check. I went with 1-week samples since that would also show trends over time. Here are the weekly results (except 13 July which is only 5 days):

Games OST Win % OKW Win %
15-Jun 524 51.8 59.8
22-Jun 420 58 58.2
29-Jun 384 60.1 70.8
6-Jul 288 60.8 61.4
13-Jul 172 64.7 69.2
Stdev 4.73 5.72


There really aren't any wild swings. The average is more than two standard deviations away from 50%. As time has passed, the win percentages for both OST and OKW are on a slight upward trend. The number of games has been decreasing, but I don't know if that has as much to do with win rate as it does people trying a new patch and then going back to whatever else they were playing.

In general, I think the balance team has done good work for 1v1 through 3v3. There's just some things that scale really differently into larger games that are causing problems. Those problems aren't getting better over time.

(PS - sorry about formatting, it always seems to compress and make a table difficult to read)

I messaged the creator of the COH2Stats site and got a clarification. My numbers should've been:

Week Start 15-Jun 22-Jun 29-Jun 6-Jul 13-Jul
Games Played 134 111 99 70 69
Axis Win 75 64 65 46 45
Axis Win % 56.0% 57.7% 65.7% 65.7% 65.2%
OST Player % 43.7% 40.0% 41.2% 44.6% 39.5%
OKW Player % 56.3% 60.0% 58.8% 55.4% 60.5%

Axis Win % STDEV 0.048146573

There are 483 games since the patch with all players in the top 200. The win rate is pretty stable around 65% Axis. The standard deviation of win rate is 0.048 so the average is a little over 3 sigma above 50%. That means there is about a 0.3% chance that this game mode is balanced and these are just abnormal results.

I'd need to be a lot better at multivariate analysis to say if the Ost versus OKW percentage actually has an effect on the outcome or is simply a measure of popularity.

(edit - here are the 2v2 numbers, which are also relatively stabile)
Week Start 15-Jun 22-Jun 29-Jun 6-Jul 13-Jul Stdev
Games Played 619 498 407 363 325
Axis Win 300 228 196 165 153
Axis Win % 48.5% 45.8% 48.2% 45.5% 47.1% 0.013565168

These numbers say the opposite, not quite to the same degree, but in this case enough to say it's a little unbalanced towards Allies. I do think that it has a lot to do with how the units and maps interact. The 4v4 maps aren't nearly wide enough, so most engagements are going straight out from your base with little room for flanking or strategic positioning. Units are a lot more clumped together so a unit like a walking stuka, that isn't good in a small game mode, becomes great in a 4v4. There's nothing worse than having a random teammate get beat in their lane in a 4v4 and have them decide to stack their units on top of mine.

I don't think it's very surprising that smaller games tilt towards axis. A lot of times it feels like I get pushed around by Penal blobs until I get the Sturmtiger out.

Hello guys

We have a new feature! Leaderboards https://coh2stats.com/leaderboards

They are fairly similar to leaderboards here at coh2.org however they have few pretty neat features:
- History of every day. You can go back into any day you desire.
- There is compare tool, you can select other date and see the change in the rank between the current and old date
- You can see the amount of ranked players that day for the given category
- You can easily sort any column

Drawbacks:
- We keep only top 200 / you can't see lower ranks
- It's not "real-time" data are gathered once a day



---------------------------------------
So who "won" the last patch (Commander update 2021) in 1v1?
https://coh2stats.com/leaderboards?timeStamp=1623801600&type=1v1&race=wgerman&historicTimeStamp=1615161600

1v1 Wehrmacht - AshaBlois
1v1 OKW - Isildur
1v1 Soviet - pfc
1v1 USF - pfc
1v1 British - AshaBlois

Congratz!

For the current patch, we can see some new contenders!
https://coh2stats.com/leaderboards?timeStamp=1627171200&type=1v1&race=wehrmacht&historicTimeStamp=1623715200

Btw some of the names might have in "change" new even though they are old time players, that can be caused by the fact that they "dropped" from the ranked category because of the inactivity. And than played 1 match a jumped right back.

Btw so far we are keeping all the old leaderboards - however it's not sustainable, it takes 600MB/month in DB to keep all the stats - so in future we will need to delete some old records.

Would be nice if there's a top 50 filter option for matches. Mostly useless for 3v3/4v4, but nice for 1v1/2v2.

We can only query matches by players / so it's more bounded to them. For the players - Relic keeps only last 10 matches for each mode.

Hello guys

We have a new feature. Player cards! https://coh2stats.com/players

For example https://coh2stats.com/players/76561198404414770

It can display:
- Your overall standings with some calculated stats
- Your last matches


The data for both standings and last matches are taken directly from Relic. So they should be in sync with the game.

The player cards display little extra overall stats. If you have some idea how to improve it please let me know.

For the matches I will try to add additional info and stats. I think I should be able to calculate info as who did most damage in the match and display it in chart etc ...

Please let me know if you find some bugs. For example some players could be crashing the view.
Thanks

You accept donations?

On the bulletin page you can sort by 'races'. Is it possible to change to factions or will that mess up the table?

Have question, How do we need to analyze it when AT team met Random team? Top200 are most likely to meet AT teams in general so the impact is probably bigger.

Unfornatelly I don't know how to distinguish between arranged team and random team from the match data.

pagep,
SiphonX used to provide match stats that showed win ratios as far as Axis/allies by map being played.

It was pretty helpful to players and mappers. In the past the numbers had a lot of variation to them. Meaning, one time Axis would be strong on a map and the next time it was allies favored.

So if it is a lot of work and you only have a small sample size it may not be worth it. But I think you already are doing it anyway from what I have seen.

EDIT:
Here is an example:

Yes map analysis was something what I wanted to do. I didn't plan to do player cards / leaderboards etc ... but when Relic cut their own website I had to add it, so it took time from the work on maps

as long as this data is put into context, yes its very valuable

FYI I just found that there are accounts which are not on steam. Feral accounts will not be possible to see right now online. The current system works only with accounts which are connected steam.

For example steam account:
    {
"id": 5536408,
"name": "",
"type": 1,
"members": [
{
"profile_id": 3771534,
"name": "/steam/76561198267976728",
"alias": "Rak",
"personal_statgroup_id": 5536408,
"xp": 40760,
"level": 4,
"leaderboardregion_id": 4,
"country": "uy"
}
]
},


For example feral account:
 {
"id": 6556450,
"name": "",
"type": 1,
"members": [
{
"profile_id": 4412017,
"name": "/feral/97200",
"alias": "RAK",
"personal_statgroup_id": 6556450,
"xp": 149145,
"level": 13,
"leaderboardregion_id": 2,
"country": "sg"
}
]
},


I was expecting that there could be other types of accounts but I thought that this is "historic" thing as I never seen anything other than steam, so I ditched the support to make life easier ...

Hello guys

I am happy to release really cool new feature.
Full match details.

In the player recent matches, you can click on any match and it will expand to show small overview.



But you can also click on open full details which will show you exactly that.



I think it brings (probably) never before seen stats, such as:
max float on all resources, commander abilities used, points neutralized, captured vehicles etc
+ it shows other data you can also see at the end of the match (damage, units killed/lost/squads/vehicles) etc etc

For example https://coh2stats.com/players/76561198047128729
