I'm going to create a thread for people to record the results of their games, and if the response is high enough I'll do the number crunching to calculate the win/loss ratio of each army posted. If a vast number of responses are recieved I'll even be able to get win/loss ratios against each other army.

There used to be a site that did just that. I can't remember the name but I'm sure someone will.

Of course in the end it wasn't very reliable because each and every list had gone through several versions, but I think it would be great to start again from scratch now that most lists require only minor modifications.

Wow, head off to a tournament for the weekend and I get to miss all this.

Whilst I agree that Battle Reports are not the be all and end all of testing I would like to add a cautionary note. Several years ago there was a constant claim about the ineffectiveness of an unit. For the life of me I can't remember who or what the problem was but several others couldn't understand why this tester was getting these results.

On questioning and I think finally with a Batrep it was shown that they were using less terraine and a 4'x4' table and not the recommended 6'x4'. These changes made a huge difference to the results which then became clearer to those of us not understanding why the inital comments were made.

I'm not suggesting that people are testing inappropiately, just that by using batreps those of us not in the same room can understand what is being highlighted.

Note that Theoryhammer is great, but my all powerfull LatD list lost twice over the weekend in circumstances that I hadn't expected.

Hope that I haven't embarrassed anyone with my example above :blush: and sorry if I have.

Win/loss ratios may not give a very accurate representation of army list abilities.

Last year I played many more games than this year. Most of those games were against an opponent that played Marines exclusively. He was one of the players who re-introduced me to the game after a 15 year break. After the first 2 or 3 intro games, he didn't beat me again before he had to move away (military posting). Thats maybe 10-15 games where I used Orks, Tau, I.G. and Marines and didn't lose.

That win/loss ratio would be of little value. Win/loss ratio's depict player abilities far more than list abilities.

If stats are going to used then I think Hena's previous post would be more beneficial. More detail is needed (such as that which you get in a batrep) to be able to make informed decisions.

Onyx, true, in small numbers and for a small number of player. However, as the number of players and reults increases the ability of the players averages out.

Reports by 1 marine player will be biased to their abilities. Reports by 10 marine players will be reaonably average.

I'll keep track of how many different players each army has, and use that when calculating the margin of error.

I think I'm going to put my money where my mouth is on this one. I mentioned earlier in the thread that I thought the win/loss ratios from the UK tournaments was one of the most useful tools I've seen so far, much more useful than hearsay or battle reports.

I'm going to create a thread for people to record the results of their games, and if the response is high enough I'll do the number crunching to calculate the win/loss ratio of each army posted. If a vast number of responses are recieved I'll even be able to get win/loss ratios against each other army..

Such a think won't help with developing new lists though. I've pondered on doing a battle stats site kind of thing with at least following support
- what rules are being used
   - rulebook/ 2008 errata/ Marks handbook at least with extra space for any additional changes
- all army list should have a version string attached to thing
  - so basic marine or NetERC marine or F-ERC marine for example
  - Tyranids 9.0, Tyranids 9.1, Tau 4.4.3 and so forth
- all games should be able to attach the armies they used in them
   - if possible determine a good way of allow parsing what units where used and how much of those units where present
- quality of win (eg what conditions vs what conditions or amount of VPs)

This would then allow getting all kinds of information. However I've never actually managed to start coding this with perl, which was my intention.

Hena: While that would be ideal, my web programming skills barely go beyond javascript these days, I'm totally out of practice.

I think for starters a straight results thread compiled in excel will do, and if it proves successful enough I'll look at coming up with something better.

I really think we need more data than just "Armies" and "Who Wins".

Point values played and victory conditions achieved might be good as well, and even a picture of the initial battlefield.

It's a valiant attempt, but it's so information-lite as to be next to useless.  Sorry, Zombocom.

Chroma: Drawing statistics from such a detailed picture is next to impossible, particularly with the number of games likely to be reported. A straight win/loss ratio is useful for one thing at least, direct comparisons of overall army list balance, an that's all I intend to use it for. This is all the info we got from the UK Tournaments, and I found it extremely useful.

As I previously said, if this proves successful then I'll look into coding up a more complex version

Once we have 25 games reported for a specific army the margin of error drops below 10%, at which point I'll start posting current percentages and margins of error.

Without knowing the winning conditions of the games played, the "win/loss" ratio is relatively meaningless, except as the most coarse of measures.

A 5-0 win is *not* that same thing as winning by a difference of 150 VPs, but look the same on the "win/loss" table; in my opinion, you'd need a "weighted value" to types of wins, not just straight wins, to get *useful* data out of this endeavour.

Army composition is also a very large factor in determining balance.  A "win/loss" record does nothing to examine this, and it's a *very* important part of army balance.  Say, over the next month I play ten "Murder of Monolith" games and I dominate, winning 8 out of 10 games against various armies... while someone else is playing a "Very Very Venator" army, because they like Flayed Ones, and gets trounced 8 out of 10 games against mixed armies...  without examining composition, those results come out "balanced" in analysis and are as useless as a single battle report that says, "See, they can lose!"

Could we just take a step back a second here and check that we all have the same aims in mind? So what are we trying to determine when having these sort of discussions on the board? For example, are we confirming that a given list is 'balanced', or that a particular unit is 'unbalanced'; against whom, and how is that determined etc? Indeed, how do we even determine whether a given unit should be represented (fluff, equivalence in 40K, 'to fill a gap' etc).

IMHO a large part of the problem would seem to be a lack of agreement on the criteria to be used - or put another way, how are we to judge objectively whether a particular claim is valid or not? For what it is worth, among other things I expect the army champs and NetEC to provide the relevant guidelines and preferably to explain their thought process from time to time so that we can all work constructively towards common goals. Equally I hope this might also reduce the currently tiresome level of general bickering and circular arguments.

With regards to Batreps, while I agree we need some extra details along the lines provided by Hena, we also need to consider what we are trying to achieve as well as understanding what is influencing the player’s decisions. So is this a competition battle with army and battlefield decisions chosen accordingly, or was the battle set up to prove a particular point etc?

Finally, statistics may be usefull as an illustration to a point, but as Chroma points out they need to be treated with great care and put in context. It may be perfectly reasonable for the average person to travel at 70mph on a motorway on a sunny day but quite a different matter to drive at 70mph on a small country road at night in fog and rain, and equally different if the driver is an experienced.

Tim they were playing from short edge to short edge on a 6x4 table and as a result found CC troops rather poor.

Oh and several people a while back expressed amazement at terrain density on tables with 12 pieces, they using a fair bit less :)

It is the same when determining who won the game.

Straight win/loss is fairer than, say, average points scored, because some armies tend to win big/lose big, (AMTL for example) whereas others usually have tighter games. The margin of error would be thrown off due to this, but it wouldn't be calculatable.

Again, this is just a simple test intended to get win/loss ratios, nothing more.

I don't intend this to be used as a tool for discovering whether certain builds are effective; that's best tackled in other ways. All that's intended to be drawn from this is an average idea of how the armies are generally performing.

If they all turn out in the 40-60% range then nothing further needs doing on this front. If some armies tend largely outside this range then we know where attention needs to be focused, that's all.

I'm not looking to draw huge amounts of data from this project, or to start drawing conclusions based on it, just to get a general idea of current army balance relative to each other.

Actually, since the data you're looking for would be a subset of a larger gathering of information, more could be made out of anything analyzed and one could still look at that simple win/loss ratio while also allowing for a richer analysis.

It's easier to get everyone to submit that data now, rather than ask for more information later, when they may have forgotten it.

Fair enough, I'll edit the thread to ask for scenario points scored, as that is at least averagable.

Psrticular build types aren't really possible to analyse in this way, so I'll leave them as optional for now.
