I was going to contribute to the fairly popular "Adept Discussion" thread in the General SC2 forum, but decided against it. To build up arguments I summarized the outcomes of major and premier tournaments, recorded on TL. I created this blog just to have a place to store the result.

The outcomes of the premier and major tournaments listed here by race.

LotV
47 major tournaments recorded, winners (t/z/p) 10/24/13, runner ups (t/z/p) 19/19/9
27 premier tournaments recorded, winners (t/z/p) 9/8/10, runner ups (t/z/p) 5/11/11

HotS
103 major tournaments recorded, winners (t/z/p) 17/41/45, runner ups (t/z/p) 29/36/38
87 premier tournaments recorded, winners (t/z/p) 30/22/35, runner ups (t/z/p) 20/37/30

WoL
94 major tournaments recorded, winners (t/z/p) 26/34*/34, runner ups (t/z/p) 27/36/32
95 premier tournaments recorded, winners (t/z/p) 37/31/27, runner ups (t/z/p) 27/35/33

* and TLO won one playing random, which is why there is one more runner up than winner

However, these numbers mean nothing when discussing the game itself, as we know that Blizzard kept tweaking the game to force sort of balanced tournament outcomes at any cost. After all, this is what left us with what the game is today: tailored towards/against the personal skills of a select few. This can also explain why the win rates are so different, when comparing major outcomes to premier outcomes. Let's not forget there are people seeing a 40% win rate in PvT, which was never reflected in tournament outcomes, as recorded on TL.

OR, looking at the results of 222 discernible player names over the course of 8 years is too small of a sample to be representative of anything else than the tournament play offs, if even that.
