I got 7:50.81 which averages out to 47.08 seconds for each scramble + solve or 23.54 seconds to solve each cube. This is my first successful attempt because I botched my first one because I could figure out a way to make sure I knew which scramble I was going to do next. Now I just number each scramble and repeatedly say in my mind while solving, "I'm solving number 1, I'm solving number 1," then when I get near the end of the solve I'll say in my mind, "I'm solving number 2 now, I'm solving number 2 now" which apparently does not mess up my solving time. I tried again though and wasn't able to get sub-8 minutes. I want to consistently average sub-7:50 so I'll keep trying.
