Today, for the first time, I timed myself as I did each of my Rubik's Cubes (3x3, 4x4, 5x5, 6x6, and 7x7) with the goal of being able to do all five of them in less than an hour. My final time was 1:02:31. I'm now confident that I could do it if I devoted 100% of my attention to solving them, but it still doesn't count, and it will take another hour of my time to do so.
