A few people have asked about WTA games - here's some data you might be interested in:

(all games described here are non-live, classic games)

This plot shows the percentages of outcomes in FP WTA games:

This shows solos in full press WTA games occur about 45% of the time, and two way draws are only slightly more common than 6-way draws. I've said this before, in a few places but the really cool thing about two way draws is that I think they're the rarest result that can reasonably be called a win.

Here's the same plot for WTA gunboats:

In our data, solos are slightly more common (around 6%), while two and three way draws are slightly less common (3% and 6%). I didn't do any checking to see if this was statistically significant in any way - it's the weekend, and I have more graphs to make :)

This next plot shows the number of WTA full press games per month:

You can clearly see the bump where WTA was made the default.

A fun thing we can do with this data is to look at the percentage of solos over time - are we getting better or worse at stopping solos? Let's take a look:

I think the answer is "not really". Although there's a big spike on the left of the graph, that could just be because the sample is too small (checking back to the games-per-month-plot, that 100% solo month only included six games).

In fact, we *could* be getting worse, since it looks like there's an uptick on the right of the graph too, corresponding with the increase in games and player pool due to the WTA default. Even if I was prepared to run statistical tests on a Saturday, it's a bit early to tell from this data.

Let's take a look at the games per month for WTA gunboats:

Clearly gunboat is less popular than full press - though that's not particularly surprising. Looking at the right of this graph, the gunboat community seems completely unaffected by the change to WTA as a default.

I also plotted the solo rate for gunboat games, but it's not very interesting:

Some questions you might have:

* Did you remove games with NMRs or CDs?

No. Our NMR data was incorrect before February this year (when the RR bugs were ironed out). Similarly, removing games with CDs is a challenge, since the system previously didn't log CDs where a member CDed and then came back to the game. These issues are now fixed, and sometime I'll have a look at the NMR rate since February.

* What period does this data cover?

I used the GR dump from June, which only includes a few games from June. This is why the solo rate is so high for the gunboat games on the right - it only includes 4 games.

* Did you exclude ANY games?

Yes. These plots don't include any games which ended before A03, since those games don't have the opportunity end in a solo without CDs. For this reason, GR doesn't consider them either. Also, this only shows non-live, Classic WTA games.
