Cool video. What you're not counting are the win streaks. For example look at the win stream at 2:44 at 9796. You hit 5 in a row and 8 out of 10. Curious, anyone here ever pop 5 in a row REs? How about 8 out of 10?
I've had many 3 of 5 and 2 in a row streaks.
But there is another human factor to consider in "win" streaks: getting a schematic but one that is not desired e.g. all the Presence purples, or Redoubt Cunning blues, or worse a player is looking for a VERY specific purple and not getting it until getting the other three or four. Many - if not most - players in those situations will emotionally consider those successes as failures.
