Title: S19 Current Player Odds
Post by: FML|red7z7 on August 20, 2014, 04:45:46 am
Hey guys. I took it upon myself as a sort of fun exercise out of curiosity to calculate the odds for each of the remaining 12 players to win the season. As a byproduct of that calculation I was also able to calculate the chances of each player getting top 3 and top 7 after Round 6, which is relevant to who goes to the semifinal and who gets a gauranteed spot in the final. Hope you all find this interesting or useful and maybe I'll do more of these analyses in the future :). Cheers!

How did I do these calculations? I wrote a python script which simulated the season playing out match-by-match for one-million times, with random players winning each match each time. That means this calculation assumes each player in any given match has an equal chance of winning that match.

Some notes:

**Disclaimer: It is likely that there could be errors in the calculations or the graphs because I'm human, there are a lot of variables to account for, and I'm not being paid to do this**

(1)
First up, heres the chances of each of the players getting into the top 7 (in other words, the chance of not being eliminated after round 6). Most notable is Renaud, sk2flash, and noexxx are 100% gauranteed to not be eliminated!
*The x-axis shows how many games out of 1 million resulted in that player not being eliminated after round 6. Thus, divide by 1000000 to get the % likelihood.
(https://docs.google.com/spreadsheets/d/1ewlGZbKEdnVB6D0buIwvAGisDCgVP-6aHkXUyFU66VU/embed/oimg?id=1ewlGZbKEdnVB6D0buIwvAGisDCgVP-6aHkXUyFU66VU&oid=1478788624&zx=phpx4044ievu)

For those interested, I've provided what the cutoff scores are for the top 7 as well. The following chart shows the likelihood of each of the score-values on the x-axis being the cutoff value. For example, see that there is nearly 60% chance of 100 being the minimum score to make top 7. There is a small chance the cutoff will be as low as 90. Missing values, such as 96, are impossible.
(https://docs.google.com/spreadsheets/d/1YtvKCFSOntwubH0FxpXOubMje6yjlDPWK8yXqAaQYJE/embed/oimg?id=1YtvKCFSOntwubH0FxpXOubMje6yjlDPWK8yXqAaQYJE&oid=1300496217&zx=7xdb8hjjcxvr)

(2)
Next up, we have the chances of each player making top 3 after R6, guaranteeing them a spot in the s19 finals. Notably, Renaud has over 98% chance of getting in, while Yaws has a 0% chance of it at this point!
(https://docs.google.com/spreadsheets/d/1mtJwxe6b_AXWKnJmLZj6PIMjJMT1Xrp8odXhglSaWg4/embed/oimg?id=1mtJwxe6b_AXWKnJmLZj6PIMjJMT1Xrp8odXhglSaWg4&oid=1754787086&zx=cihlidgwo3qj)

Again I've provided the chances of each of the possible minimum values, this time for making top 3 after R6. It is most likely (with a 30% chance) going to be 115 points, but there could be a freak-accident making it as low as 105 or as high as 131!
(https://docs.google.com/spreadsheets/d/1M2BYy2i7QoO_I2VaEQjX6XzI-o99adLzpFOkfmM8rg0/embed/oimg?id=1M2BYy2i7QoO_I2VaEQjX6XzI-o99adLzpFOkfmM8rg0&oid=1221018777&zx=binkk7a69053)

(3)
And finally, here are the chances of each player winning the entire S19. It's looking good for Renaud right now at nearly 25% chance! **Edit: corrected this value. I simulated 1 million outcomes for up to R6, but after that for final it's easy to calculate odds -- 4 possible winners of the semi, and 4 possible winners of the final for each outcome of the semi, thus 4x4 = 16 more outcomes for each of the 1000000 outcomes of R6. Thus, divide by 16 million for the final rather than 1 million to get percentage! For reference, ostone has a 14% chance, and yaodintakoi has a 7% chance, and yaws has a 1.5% chance. Every player still has a chance though! **Edit: to clarify, this distribution is not the chance of a player winning the final match in isolation. Instead, it accounts for each of the matches played between R5, R6, and semis as well, and then the chances of winning the final after all that.
(https://docs.google.com/spreadsheets/d/1McsW_euLeCUKxfOK0U5gvx-2xchPwQ1hJVk7aJ2vl-I/embed/oimg?id=1McsW_euLeCUKxfOK0U5gvx-2xchPwQ1hJVk7aJ2vl-I&oid=2061014967&zx=xecdljrfom71)

Assuming this does not take player skill into account, shouldn't it be impossible for a player to have greater than a 25% chance to win s19?
Title: Re: S19 Current Player Odds
Post by: Pinballmap on August 20, 2014, 08:47:15 am
I think thats correct . 25% is the maximum when you are playing the finals. waiting for the graphics though.
Title: Re: S19 Current Player Odds
Post by: FML|Mage on August 20, 2014, 08:52:05 am
Maybe it takes in previous results so far this season and somehow factors that in for skill/chances to win.?

That means this calculation assumes each player in any given match has an equal chance of winning that match.

Oh... then yeah I'm confused by the 40% chance.  Red wake up!
Title: Re: S19 Current Player Odds
Post by: Pinballmap on August 20, 2014, 10:13:51 am
i think 40% that Renaud will get place 3 or higher makes more sense then.
Title: Re: S19 Current Player Odds
Post by: FML|WorpeX on August 20, 2014, 10:17:07 am
I think it also takes into account the amount of times a player makes it into the finals as well. Since his calculations simulate the whole season a million times, its to be assumed that Renaud makes it into the finals more times on average then the rest of his peers, which is why he has a higher chance of winning the season. So, yes, he has a 25% chance to win the finals but since Renaud makes it into the finals more times then everyone else in his calculations, his odds of winning are higher.

Yeah!  This is what I meant to say

Really!

Why do I get the feeling none of you believe me

Oops, I had linked the images directly from my google drive and forgot to change the share settings. Should be fixed so you can see the images now!

Assuming this does not take player skill into account, shouldn't it be impossible for a player to have greater than a 25% chance to win s19?

Not quite -- the equal 25% chance applies only to individual matches. When you factor in current point standings, and multiple matches being played, you get a distribution that reveals different chances for each player after each round.

That's exactly right. That should also be more clear now that you can see the graphs and the numbers on the axes. Just divide by 1000000 to get percentages.

Images work for me now, this is incredibly awesome!  I hope to see some more stuff like this in the future though I'm sure it's a lot of work.

Very nice job though

Fantastic job, Red. I really appreciated the graphs figures and everything. It seems plausable. Although something within me is making me think: "never tell me the odds"  :icon_wink:.

Basically, I need to hope Ostone or Flash finish 4th in their game on Thursday and that neither of them wins. GO SOSO OR SEKSI!
Title: Re: S19 Current Player Odds
Post by: FML|Renaud on August 26, 2014, 08:28:54 pm
but the good news is that we will play each other (again) in the last round!

unless someone switches us out... but since we are pretty much the same kind of player it wouldn't make sense

This is useless as we all know, Renaud will be S19 champion using his double gold card + cloak of invisibility card in the final!

Yep, I like looking at the odds and everything but... in the end you just need to win every game and you will be fine :D

Nice but didnt you say that Renaud has a 40% chance to win the finals in the starting post? (I can not see the pictures of the original post) Now it dropped to 25% (which makes more sense to me since it s 1/4 for the finals players)
Title: Re: S19 Current Player Odds
Post by: FML|red7z7 on August 29, 2014, 03:22:45 am
I actually edited that figure even in the original post because it was wrong. It actually was like 25% for renaud at the beginning of round 5, which was still drastically higher than any other player. (All the percentages from the 12 players summed to 100%, so the fact that he had 25% was very good).
