IQ Score basically shows your correct/incorrect answer ratio accumulated from all your tournaments (except SNG) over the last 30 days. In example, if you are new player and you participate in tournament of 10 questions and answer correctly all of them you will get IQ Score of 100. Then you participate in another tournament and again answer all questions. Your IQ Score is still 100. Then you participate in third tournament and answer none of the questions correctly. You get zero IQ Scores for tournament, but your general IQ Score is not 50 but 67, because (100 + 100 + 0)/3.
When player logs in into IQ Wars and notices that his IQ Score has decreased or increased it means that results from tournaments older than 30 days are excluded from IQ Score. In other words it means if player played only one tournament and answered all questions correctly, but didn’t play any tournament anymore, he will have IQ Score of 100 for 30 days, but after his IQ Score will become 0.
