Dotabuff data population in General Discussion

    Can some dotabuff staffs provide some insights into the data population? This will give users a better idea of the credibility of dotabuff data.

    Examples are
    1) Number of unique users that are being tracked? Versus official Valve data?
    2) Completeness of matches that are being tracked? Versus official Valve data?
    3) Average and median MMR of the users that are being tracked?

      Storm Spirit is literally a force of nature--the wild power of wind and weather, bottled in human form. And a boisterous, jovial, irrepressible form it is! As jolly as a favorite uncle, he injects every scene with crackling energy. But it was not always thus, and there was tragedy in his creation. Generations ago, in the plains beyond the Wailing Mountains, a good people lay starving in drought and famine. A simple elementalist, Thunderkeg by name, used a forbidden spell to summon the spirit of the storm, asking for rain. Enraged at this mortal’s presumption, the Storm Celestial known as Raijin lay waste to the land, scouring it bare with winds and flood. Thunderkeg was no match for the Celestial--at least until he cast a suicidal spell that forged their fates into one: he captured the Celestial in the cage of his own body. Trapped together, Thunderkeg's boundless good humor fused with Raijin's crazed energy, creating the jovial Raijin Thunderkeg, a Celestial who walks the world in physical form.

        1. This is hard to quantify, but i think the last time we checked it was estimated that a significant % of active players had their stats enabled. Several millions have profiles. An exact number is really hard to nail down for a lot of reasons.

        2. We collect data for all public matches. This includes all matches played with public MMing. It excludes practice matches and private lobbies. It also includes matches where no players have stats enabled.

        3. I don't have the avg MMR # off hand, but we've seen that it tends to be higher than average. I would anecdotally guess in the ~3k+ range.

        We've noticed a trend which is that players have their stats enabled tend to be of a higher skill, and those who use rating buddy tend to be higher MMR than the average. I imagine there is a large portion of the bottom 25% of players (skill wise) who never seek out community sites and that contributes to both them being bad and their under representation on sites like ours.

        When you play a game there is a clear correlation between the # of people who have their stats enabled and the MMR of the match. Obviously there are a lot of exceptions to this rule, but generally speaking.
