Tried a 1v1 game today as Zerg. In my 1st placement game, my opponent was a random race gold player. Turned out he was protoss. I won this game by massing ultras. Checked out the score screen later and found out that my apm was 172. Wow. If I recall correctly, I had never achieved such a high apm before. Probably due to my panicky larvae injections I think, haha!
