STAT CHECK: ACS Groups

Threaded Linear

Earlier I predicted the ACS of every player at Champions. I made a post after the first round comparing how right I was as well. Now that the group stages are done, its time to analyze.

TLDR: The results have gotten closer to my predictions since the first round.

The ACS is what I predicted, the Groups is their ACS after groups, Diff is the difference between the two, Rank is their rank based on ACS, and R Diff is the difference in rank.
My predicted ACS has an average of 206.9 while the Champions ACS is 198 so there will be a lot of negative numbers as I predicted too much ACS in general. The bulk of players are more towards the middle than I had originally predicted. I had previously after the first round, been wrong by an average of 29.62 ACS per player, but now it is down to 23.25 ACS per player. The larger sample size took out a lot of the variance.

The Good: Derke, DubsteP, d3ffo, Mazino, Sushiboys, and dispenser all did better than I predicted. However, they all still have tougher matches ahead and some of them will drop.
The Bad: ScreaM, mwzera, PTC, frz, Rb, and ade all performed worse than I expected so far. ScreaM could still bring it back.
The Interesting: ade managed to be one of my biggest overpredictions despite me picking him to be 2nd to last. Yikes.

Also after the first round I had the players rank wrong by an average of 18.7 per player and now it is 16.7.

pretty amazing work but this forum is mainly children who like to make fun of regions. Trust me, more people will appreciate your post if you post it on the valorantcompetitive subreddit.

its definitley biased towards NA because its an American website but I would say the average age is older and people might appreciate stats more. More than the "____ region is shit" people on here which compose 50%+ of the userbase

Both have shit userbases but better posts end up showing on the reddit because of how reddit simply works. And it's mostly just a loud minority here. I guess the 2heads just use the website more... oh wait. fuck.

idk what you on but the most upvoted threads are usually the stats threads

Getting more accurate on all fronts, probably because more players are getting a better true sampling of their usual ACS. The champions ACS distribution is getting closer in shape to the prior mean ACS and approaching its mean.

Round 1 plots:

Post-groups plots:

Round 1 scoring:

Total prior error = 2582 Total pred error = 2436 Total rand error = 4183.0
Average prior error = 32 Average pred error = 30 Average rand error = 52

Correct predictions(predicted acs): 30/81 = 37%
Correct predictions(prior acs): 24/81 = 29%
Correct predictions(random acs): 17/81 = 20%

Post-groups scoring:

Total prior error = 2107 Total pred error = 1919 Total rand error = 3465
Average prior error = 25 Average pred error = 23 Average rand error = 42

Correct predictions(predicted acs): 42/82 = 51%
Correct predictions(prior acs): 35/82 = 43%
Correct predictions(random acs): 26/82 = 32%

Total prior error is the absolute difference between the predictor and true ACS. The average error is just the mean of those differences. A "correct" prediction is categorized by whether it falls within +/- 20 ACS of the current champions ACS.

Note: The computed random predictions are different datasets(because I overwrote the other one by accident)

Dang your stats are next level.
