Well, let's see... Trials of Osiris has been active since May 22, 2015. Since that time, there have been 39 weekends, which we would assume means 39 Trials events. This is not the case, as Trials and Iron Banner were briefly done away with after the release of The Taken King. Matches were postponed at September 14, 2015, and resumed on October 13 of the same year, leaving 4 weekends where it did not take place. This means that [b]since the release of House of Wolves, there have been 35 Trials of Osiris events.[/b] In each Trials event, there has been 4 days where it has been active, Friday to reset on Tuesday. This gives us a total of [b]140 Trials days[/b]. With this number, we can calculate the average matches OP has played per day, his total play time in Trials, and the maximum number of times he could have gone flawless. 10,000 matches total / 140 possible Trials days = [b]about 71 Trials matches per day(!) or 284 per week (71 per day * 4 days per week)[/b] 10,000 total matches * 10 minutes average per Trials match = [b]100,000 approximate minutes of Trials play time[/b] 10,000 matches / 9 matches to go flawless = [b]a maximum of 1,111 flawless Trials runs (that's a lot of Adept weapons)[/b] Keep in mind that these numbers are all approximate.
