I thought it would be a good idea to demonstrate how I solve the edges on the 5x5x5. I think this method is at least as fast as the bigcubes.com method. I average around 60 seconds with the "advanced" variation of my method.
The basic idea is to use the 2-at-a-time method that is used by a lot of people on the 4x4x4. If you don't know it, I suggest you learn it first from bigcubes.com. For the 5x5x5 you don't match a wing with another wing, but you match a wing with it's center-edge. If a wing is matched with it's center-edge I call this a semi-pair. If you try this method on a 5x5x5 you will see that it works very good sometimes, but very bad other times, especially if you try to use 4-at-a-time or 6-at-a-time. This is because a center-edge has 2 wings. To avoid those problems you start with a semi-pair and keep it there all the time. If a semi-pair is not available directly after doing centers you have to creat one, which is really easy. The way I perform the edge-pairing is that 0. I put the semi-pair on the upper half of the Left-Front tredge-spot. This means my "1st working wing" is in the lower part of the Left-Front tredge-spot.
1. I then put the first edge-center at the Front-Right-spot
2. I then do a d-move to form a semi-pair at the Front-Right-spot. The "2nd working wing" has been moved to the Right-Back-spot
3. I then replace the first edge-center at the Front-Right-spot with the 2nd edge-center.
4. I then do a d-move to form another semi-pair at the Front-Right-spot. The next "1st working wing" is now at Left-Front again.
There are 3 special cases "Parity before the end", "flipped wing", "full 3-cycle" and they can be handled in different ways. Analyze the examples to find out how I do that.
I have developed a scramble that keeps the centers solved, the edges scrambled pretty well and that is easy and fast to execute. To follow my examples you should have a 5x5x5 cube with a "regular" Blue-Orange-Yellow colorscheme. The scramble should be executed with white on top and green on front. DFRBLU are outer face moves, dfrblu are double layer moves. I don't use slice moves at all.
To make it easier to clarify any questions that people might have I will update this first post with general information. I will use the next five posts for the following examples: Beginner, Intermediate, Advanced, Expert, Other additions such as an example with parity and a worse beginning.
OK, lets get started:
