I would probably get pushed in after it...No way, had I tried that, the sequence of videos would have been: 1) me solving the cube in front of the Big Ben; 2) my wife throwing the cube to the Thames river.

On the menu today: one bld attempt on each of my 3x3 cubes. Result:
It's getting kind of frustrating to mostly have one mistake/solve. Times were in the 4:30-6:30 range, 2-3 minutes memo and 2:30-3:30 execution. I think all of the flipped edges/corners were memo mistakes, either I missed a flipped piece during memo, or memorized the wrong letter for some piece.

View attachment 5677
4x one flipped edge or corner pair
2x one 3-cycle executed in wrong direction
1x flipped edge pair+edge cycle executed in wrong direction
1x messed up setup moves
= 8/8 dnf

Still those are all pretty close... I woud be totally fine with these results today
Nope, definitely not giving up! I'm actually very happy with the progress so far. Still a week ago it was more like 6-7 minutes memo, >5 min execution and a lot more messy results. Times are dropping very fast as I'm getting more used to the cycles. I also started compiling a list with setup moves for each edge cycle. Not intending to learn them all by heart at this stage, but while making the list I'll notice which cycles are hard to figure out and I can memorize those cases. Once done with the list, I might also replace some tricky cases with standard comms if I find a better solution that way. The hardest cycles to figure out with my system are usually those cases that have 2 stickers interchangeable with an M or other slice move, so comms should complement these very nicely.You're in the beginnig of the road. Dont give up - in few months you will be 100% accurate.

Thanks! Yeah, multiblind would be a bit crazy at this point. Maybe I'll wait until I have at least 2 successful 3bld solves before attempting multi... But I'm sure I will eventually want to learn that as well. This is fun!Same here! That would be close enough to success for me right now. I was gonna ask if that had been a multi-blind attempt but now I'm reading again, where you explain the memo and execution time for each so I assume those were individual BLD attempts but with different cubes.
Thank you!You are making impressive progress JanW. They were all very minor errors that will become increasingly rare. I do a lot of them myself as I get sloppy with things like flipped edges and parity. I need to come up with a proper system to follow.
Thank you!
What kind of system do people usually use to spot and memo flipped pieces? So far I've just looked briefly over the cube at end of memo to see if there are any pieces that need flipping, then memorized the location visually (location of piece for edges and location of white/yellow sticker on corners that need flipping), but obviously this is not working very well. Sometimes I don't notice them in inspection, and when I do notice them I often forget to execute them, because they are not a part of the list of words/syllables in my memo.
Thank you!

Chree, theres easy trick for twisted corners R U R' U' done twice than L' and undo U R U' R' twice and L. It works with setups, same on the L' U' etc. I think you will figure it out. For 3 corners you can do sune with U perm to undo permutation of edges.
Great trick! I've seen it mentioned before but didn't see the versatility of it. It's a commutator where the insertion phase rotates two different corners and you can do the interchange with either of them, so L moves for twisting two L face corners or D moves for twisting 2 D face corners. The cool thing is that you can also use this to twist 3 corners (UBL, DFR and any other L or D face corner) with a 2 move interchange. First move brings UBL or DFR out of it's spot and replaces it with the third corner to be twisted, second move places the piece you brought out into the opposite corner (UBL or DFR). For example twisting UBL, UFL and DFR would be [R U R' U' R U R' U', L' D2]. I think that could be faster than the sune and U-perm, which seems to require some AUF moves as well. But you need to be careful when twisting 3 corners with this one, it twists in different directions depending on which direction you do the interchange (if you use R U R' U', UBL travels to UFR = clockwise, UFR travels to UBL = counterclockwise).Chree, theres easy trick for twisted corners R U R' U' done twice than L' and undo U R U' R' twice and L.

Nice idea, I'll try this! Y is already in use, but I could use D, which isn't used yet as it's on both my corner and edge buffer.I've been using Y and Z for twists and flips. YF means twist the RFU corner clockwise, ZF is counter-clockwise, and either can mean a flipped edge. It's probably not efficient but it fits into the Journey Method so it works just fine for MBLD. Also, since you use two letters for a single twist or flip, you can still identify parity by an odd letter at the end of your memo.
Thank you!

Google did a decent job of translating it to English on my phone.I think a lot of blinders use it, but I dont know any english tutorial about it. I've learnt it from Maskow's tutorial. And I know Jałocha and Zalewski used sune/antisune Uperm for 3 corners on top*, and if they are on bottom Jałocha used: R U R' U' R U R' D R U' R' U R U' R' or for 3 corners (very rare!) 2*(R U R' U')D' 2*(R U R' U')D' 2*(R U R' U') D2. Etc. Theres a lot combinations as you mentioned.
I have a blog where a put some stuff about speedsolving, photos etc. It's in Polish but I think photos dont need to be translated. Here are few photos from Gdańsk Rubik's Cube Day. Just click in the first and you can see them all in bigger size.
Edit: *Zalewski's algs:
R U2 R' U' R U' R' U2 R' U2 R U R' U R U2,
R U R' U R U2 R' U2 R' U' R U' R' U2 R U2
R U2 R' U2 R' U' R U R U' R' U2 R' U2 R U'
