Could someone explain how these rankings work? 3/3 > 4/5 > 2/2 > 3/4 > 6/10 ???

 

[RyanReese09]

For every cube you miss, you get 1 point deducted from your cubes that were succeeded. It's off a point system.
3/3 = 3 points
4/5 = 3 points (in a slower time so it's ranked lower (presumably from your example). 4/5 is 1 cube off. So 4-1 = 3.
2/2 = 2 points. Lower then 3 points.
3/4 = 2 points (slower time presumably). 3/4 is 1 cube off. 3-1 = 2.
6/10 = 2 points. (obviously slower time). 6/10 4 cubes off. 6-4=2.

Points = cubes solved - cubes unsolved

3/3 = 3 - 0 = 3
4/5 = 4 - 1 = 3
2/2 = 2 - 0 = 2
3/4 = 3 - 1 = 2
6/10 = 6 - 4 = 2

Results with the same score are ranked by time (fastest is better) so a 2/2 is more likely to beat a 3/4.

Thanks for your insight Mike. I found that rushing memo (just placing the image there is enough) is the key to fast times (for me). Though during review I do have to spend slightly longer to ensure recall, but if you do the math, if you spend longer on each location during memo, that time adds up. You'd still be reviewing it anyway (the time saved would be very minimal during review) so I just took the good route and chose to rush my initial memo . Works for me.

I've been sort of doing that for the past two weeks, but probably not enough. This coming week I'm going to really try to go all out and rush my memo, and then do longer review.

My memo might be easier if I weren't always doing it at 2:30 in the morning. Quite seriously, it seems like I often do much better in competition, probably because in competition I've actually had some rest before my attempt.

How should I approach twisted corners/flipped edges? Right now I just have the cubes put on the table not in a straight line, indicating something is up with the c ube. Normally I'll either have an object in a location say "FLIP CoMbs or whatever, if it's 2 (in that example) and I'll have to pure flip hte C and M pieces). Twisted corners I just kind of have to "visually" remember it's twisted. I hate it since I know it has a huge potential for DNF>

Should I have a location in my room(s) purely for this type of thing?

Obviously, that's up to you, but I do use a separate location for flipped edges and another one for twisted corners for each cube. Often those locations are empty. It works fairly well, and I have plenty of space in my rooms for the extra locations.

Wow! Thank you, I cant believe I didnt think of something like this....
Ive always been memoing them as 1 cycles (Like UL to LU, or CQ, or Croquet for me)
of course that is inefficent xD
I might start to do a mix of what you two do: Offset the ones where I need to check the location, and put the flips and twists in those seperate locations.

How are you MultiBLDers memoing the last piece in parity cases? You have images for letter pairs. Do you have a separate image for a single letter?

 

[aronpm]

I just memorize the letter as a sound fitting in with the sentence. Or I just make an image out of it using a random letter, and just drop the last letter when I get back to it because I know that there's parity.

I do what I think Ryan does:
In our journey, roman rooms, linked list, etc, we would slice an image in half, symbolizing that that is where you are supposed to stop. When I see the image that is in half, I know that I have to do a weird bh parity case

[RyanReese09]

It depends but sometimes I'll have an object saying it (if sexual scene and the letter is "A", I'd have "AHHHHHHH") and just know it's A.

It depends on the situation but I'll do the image in half. If I'm transitioning from edges to corners and I have an image that has one letter from each I'll have a imaginary blue wall between the image signifying to switch over and do parity.

 

[EricReese]

I think I might be misunderstanding parity, my successes so far have not had parity, and I might know why

Ok lets say I have these scenarios, please explain how I would approach parity for M2 way, and for regular OP way, assuming I do corners first then edges in execution

memo is like 5 letters for corners, and a pure 2twist, I would for OP, do the 5 corners, then do the 2twist, then I would do a y' rotation, do my R(b)? alg, undo the rotation, then solve my edges, then do another y' and do the r perm again? Dunno about M2 way


With M2, I find it easier if I just let the buffer solve itself, then break into a new cycle, so I dont have to keep track of where the buffer piece is, and know where the piece has to end up for all the edges to be done, is this good practice?

 

[RyanReese09]

The R perm that switches UL and UB edges (and the corners) (you do this after you do corners and it's odd amount)

After this-
For edges M2. Solve them. After you have to do U' F2 U M2 U' F2 U, then R perm again. Solved cube

For edges Old pochmann, solve them. IIRC you don't need to do R perm again.

Using Old Pochmann for 3x3x3 and assigning letters to stickers, how should one remember which pieces are not yet solved when it is needed to break into new cycle?

 

[MaeLSTRoM]

When the buffer would be solved, choose another unsolved peice and ontinue, do not memo the buffer.

If you used tape or an equivalent to bandage a 4x4x4 could you use it in MultiBLD?

If you're just beginning to BLD, you may have to trace back your memo and see which pieces you haven't covered yet. When you've done it long enough you tend to have a feel of which pieces you haven't memo-ed.

Well doh, that's what I'm asking. HOW do you know which are not yet solved?

Yeah, I'm just beginning and I try to trace back, however I never quite seem to get it... I end up picking a place and going through whole memo checking if that place is solved or not. And that takes ages.

 

[Phlippieskezer]

When I started out, I tended to trace back and put my fingers on the pieces I've already memorised. In the end, the pieces I have not put any of my fingers on are the pieces I have not yet covered. Quite simply, really. That's when I break into a new cycle and continue the solve... If all the pieces have a finger on them (I tend to take my fingers off a layer if I've covered all in that layer... I don't have 12 fingers), then the cube should be solved.

Of course, you get the hang of it naturally after a while...

Sorry, that's probably not crystal-clear, but I hope it helps...

Ahh, yeah, that's what I tried too. However, I first check if all of the edges are solved (quite easy, number of shoots = unsolved peices + cycles - 2). I got my fingers all tied up though, lol. Guess I'll have to stick to this though, as I can't think of anything better (other than visual, which I suck at).

 

[ilikecubing]

The best edge memo technique for you really depends on what you're already using for corners.

Cool Indeed,So whats the best edge memo technique if -

1) If I use visual corners,memo corners later and execute them first

2) If I use sounds for corners,memo corners later and execute them first

3) Letter pair for corners,memo them first and execute them last.

 

[Rpotts]

1) Letters
2) Letters
3) Mmmmm maybe letters but idk
