How to read the win rates on PickStudy
Every ranking on PickStudy shows three numbers: win rate, pick rate and games. Reading them together is how you tell a genuinely strong brawler from one that got lucky in a handful of matches. Here is where the numbers come from and how to read them.
Where the data comes from
Every morning (around 07:23 KST) we pull data from the official Brawl Stars API provided by Supercell. We take top players from the global leaderboard and nine country leaderboards, up to 450 players, and collect their recent battles. Duplicate battles are removed, and the last 7 days are combined. While the site is still building up history the window is shorter, and the exact period is always shown in the "Period" box at the bottom of each page.
Trophy and ranked battles are calculated separately. The same map plays very differently with random teammates than with a ranked draft.
Win rate
The share of games the brawler won. In Solo Showdown a top-4 finish counts as a win, otherwise the numbers would be tiny. Duo and Trio Showdown are left out because teammates have too much influence.
Why win rates often exceed 70%
Our sample is top-ranked players. They win more than average by definition, and in trophy matches they sometimes face lower-rated opponents. So the overall average sits above 50%, and that is expected.
What matters is the order within the same map. Since every brawler on a map is measured under the same conditions, "A wins more than B here" is a meaningful comparison.
Games: how much to trust a number
Which is more convincing: 8 wins out of 10 (80%) or 210 out of 300 (70%)? The second one. Small samples are mostly luck.
PickStudy handles this in two ways:
- Brawlers with fewer than a minimum number of games on a map (currently 15) are left out of that map's ranking. Showdown uses a third of that, since each match has many players.
- Rankings use an adjusted score, not the raw win rate. Small samples are pulled slightly toward 50%, as if about 30 average games were mixed in. That's why a brawler with a higher raw win rate can sometimes rank lower.
Pick rate
How often the brawler was chosen on that map, out of all picks. High pick rate means top players trust it there. Low pick rate with a high win rate can be an under-used gem; high pick rate with an average win rate means popularity is ahead of results.
When to be careful
- Right after a balance patch: the 7-day window still contains pre-patch games for a few days.
- Brand-new brawlers: small samples, often played only by people who are already good with them.
- New maps and event modes: rankings can swing a lot from day to day. Pages with very few games are kept out of search results.
- A different skill bracket: data comes from top players, so mechanically demanding brawlers may do worse at lower ranks.
In one line
Look at the order within a map, check games for reliability, and compare pick rate with win rate. See today's maps on the home page, all brawlers on Brawler Tiers, and the method on the About page.
