Learning speed optimal 3style and a letter pair list was the best decision I ever made. This momentum of improving doesn't feel like it's coming to a halt at all :)

Great work! Mind sharing your edges list if you're done with it? Would like to compare.

A lesson for all who want to improve in BLD but haven't yet decided whether to start learning commutators or not.
GJ as always
edit: now you are totally better than me at 3x3 BLD

Thanks! It's nice having someone as good as you constantly giving my PB posts a GJ even though sometimes I kinda spam this thread haha

Really nice! You might be sub me now

Thanks man! Doubt I'm sub you though, these are overall PB's for me right now and aren't sub you :p

Thanks! I'll post a list once I've got it all written out, although I probably need to update my corners list too since I've changed a decent amount of comms from there...

I should REALLY start learning atleast some corner comms, I know all comms for UBR already tho. Memo is around 30 I guess

First decent 5x5 BLD solve since I started learning new algs. Notice lots of pauses between them (in the first half of execution, when solving x- and t-centers). I hope I can eliminate them soon, then sub-4 is inevitable ^^

This is really cool to see! How exactly did you go about optimizing your comms for 5BLD? The reason I'm curious is because I find that my lengthy but fast <RUD> corner comms don't fare so well for big BLD, even though they're great for 3BLD. I can only assume you're going for a happy medium between low rotation count vs low movecount. Also, which buffers did you learn for centers? (I'm assuming you probably didn't learn more than one buffer for x/+ even though I'm sure you do floating buffers).

I don't use floating, I'm not even sure I know how to do it (lol). My buffers are: UF, Uf, UFl; UBR, Ubr. You can check my algs here: https://yadi.sk/d/w9WhVIUdackc7 -> Roman's algs list (the first sheet "info" is raw yet; also, you have to download it to see colors and annotations).
Since the only criteria for an algorithm to be good is speed (and not convinience nor TPS), then the basic approach for optimizing algorithms is find all possible algs for a single case, make ao12 for all of them and choose the fastest one.
I was really amazed when saw Gianfranco's 3BLD Mo3 video three months ago, all three solves seemed to be without a single rotation and very fast. I started edit my algs hoping that removing rotations will speed up execution (I even replaced a lot of x' with 4Rw'/4Lw) but it turned out on big cubes rotations doesn't affect speed as much as moves themself. On the 3x3, (x'+alg+x) is slower than (Rw'+alg+Rw), but on 5x5 it's not. I only discovered it when did ao12s, before that I was believing I'm doing faster :D So in conclusion I think I'm more inclined towards low movecount.
As for buffers, I am recommend you to use same buffer pieces for centers as for corners and edges. For example, if your corner buffer is ULB, make sure your x-centers buffer is Ulb. DF edges mean you have to use DFr or DFl wings buffer. I'm not sure though what you have to do with t-centers ;)
