k4 but for 5x5 http://snk.digibase.ca/k4/ it can be applied to 5x5, but alter the commutators a little bit, it is a hard method, GL if you wish to stick with it

ummm i am so new to this
case 1: can you explain the # a little more
case 2: what is a comutator?
case 3: can you elaborate on what a 5 cycle or a 3 cycle is?

Case 1: # stands for the algorithm that you would use to solve that other case. The idea is if you have to flip two adjacent edges, move 1 so they are opposite, flip them, then return the edge to where it belongs.

Case 2: To understand comutators have a look here at our wiki.

Case 3: a 5 cycle is where you move piece 1 >2>3>4>5>1. This creates a cycle with 5 pieces. In general an n cycle is piece 1>2>...>n>1. You did not say weather case 3 was a 5 cycle or a 3 cycle and a 2 cycle. Even though both pieces that have to move to the right may have the same color, there are unique pieces and must go to the right spot.

Also for cases 1 and 2 I did provide algorithms that could be used.

The first time is the number of seconds each step takes, and the time in parentheses is the total elapsed when each step is finished. I average about 2:15-2:20. What steps should I work on?

21 for 3x3x3 stage seems quite slow, considering your 3x3x3 times...
i think your balance between centres and edges times is okay, 21 for l4e is pretty slow though, maybe you need to work on efficiency there?

I think the 3x3 stage times can be explained by a combination of having to make a cross without inspection, 5x5s being harder to turn than 3x3s, and my 5x5 in particular being really bad. I'll work on it though.

I just do a whole lot of "slice over, R U R' F R' F' R, slice back" for L4E. Also I have to do the 4x4 parity alg half the time. Is there any way to improve that?

it's probably worth learning a few more l2e algs! i think most of them are very good (or at least, considerably better than setting up to the common parity and then solving that)
also, M' U2 M is super useful for l4e, especially if nothing's paired at the beginning

I saw your solve video you put up as well; centers are fine for your averages, I have 30-35 second centers and a sub-1:55 global average.
I haven't separated my splits for F8E and L4E, but I'm around 50-55 for all 12 together, and I would guess I'm around 15ish on L4E.
Definitely learn those L2E algs, other than that I can't offer much advice as my L4E is really bad.
If you are trying to get serious at 5x5, get a Yuxin. It is so much better than a SS or Aochuang and less than half the price of a Huachuang. That should really cut your 3x3 stage, I'm around 20-21 with a Yuxin while averaging barely sub-15 on normal 3x3.
To wrap up, though, at this point your best bet besides some L2E algs is just to invest time in solves. I cut down to around 2:00 flat without focusing on anything or learning any sort of L2C or L2E.

I decided to add "stage solving" to my 5x5x5 brute force solver. So the reduction method solves centers first. Rather than code it to build blocks, I wrote code to have the program pre-solve every possible arrangement of exchanging up to 4 centers simultaneously, ignoring what happens to the edges and corners.

I don't know if any of these oddball Algs would be of interest to the group. I can guarantee each is the shortest number of moves required to do any of these center swaps.

Edit: For example, the longest center solve for 3 centers exchanges between the top and front faces requires 11 turns:

I need some tips on speedsolving the 5x5. I have been practicing a bit, and I want to start working on tricks to improve my times. If you have any, please let me know. Thanks
