Ok, its not related to Speed-solving, hardware, or the other categories, and I'm not a complete beginner. It's about the 7x7.
When I learned big cubes, I had always solved opposed centers in pairs. This whole "one center at a time" idea is very novel to me. I didn't have commutators with my system; I didn't have too many issues at all actually, yet somehow it was a little bit harder (especially on the last two). If I were to explain the system, would anyone out there be interested in giving it a shot to compare times with? Would anyone want to give it a shot out of curiousity? It's a billion times faster (hyperbole) on the 4x4, but I haven't timed myself on anything due to the lack of a decent timer. Would anyone care to hear about this method?
Another thing about the 7x7x7- Edge parity. I use reduction (if you couldn't tell), and when solving the edges, I first make a 3 block long edge in the center of every edge, and then extend both sides out one, making it 5. Wow, I'm awful at explaining. In any case, I've noticed the parity seems to come in pairs - if you have a parity issue on the inner edges, you'll get a parity issue on the outer edges as well. Does everyone else experience this? Or is there a different method that everyone else out there uses that makes my parity question inapplicable? It's not a problem, its just a pattern I noticed and thought I would point out.
I know I'm not the best at explaining things, but i hope you find this makes sense. Thank you for your time.
