Ah, so you might be trying the same amount as me this week (if your cubes come real soon)?
So if the new rules changes go through, I'm wondering if I should just keep going with the most I've ever solved plus one (currently 8), or if I should drop back to 3 cubes, since the most I've ever solved at 8 minutes per cube is 2. (It's frustrating, because I did 5 cubes in 40:13 - just 13 seconds too long.)
At least you're well under the limit - you don't have to worry about it. Very nice job!
