Holy mother...I just solved the cube in 12 seconds... My average is 40 seconds, I skipped 2 steps, and my F2L was about 5-7 seconds. My only witness was my mom, she started freaking out, haha.
While averaging 27.xx I once did a 13 second solve, no skips. I was really excited about it. Then I realised that the timer had a built in 10 second countdown, that I hadn't noticed.
