In FMC, what happens if the first move of your solution undoes the last move of the scramble?

Is it allowed? If so, how many moves are you allowed to undo?


EDIT: does anyone know where I can find a program/website that solves optimal EOlines from various angles? The only EOline solver I know only solves from a fixed angle.

First question: I think if you can explain your solution, then it's fine to undo a move or two at the end of the scramble.
Edit question: jarcs could, but as you can see, there's a slight problem with that...

@TDM, you are sub 15 so how long does it take you to do f2l and cross+ f2l?

practice all f2l cases from all sides algorithmically.You will improve your tps along with your f2l.

If your F2L+cross was 6 seconds, you would probably be sub 10. To be sub 15, I would say that a sub 10/sub9 F2L would suffice. For comparison, my LL Ao100 is exactly 7.00, and I average right about sub 20, so that means that my F2L is about 13 seconds. My LL also sucks pretty badly, and I don't even know full PLL, and about 25 OLLs. A 5-6 second LL is fairly easy to do if you know full OLL and PLL.

I'm not globally sub-15, but I get plenty of sub-15 solves. On 14.xx solves, I will usually finish the F2L (whenever I say F2L here, I mean full F2L, or Cross+F2L steps) in about 10 seconds. Then, I can usually get a 14.xx time because I know full OLL and PLL, so LL usually takes 4 seconds. Sometimes, I will get a low 15 time, though. When I get 13 or 12 second solves, usually I finish my F2L in 7 to 9 seconds. And sometimes, amazingly, I will finish my full F2L in 6 seconds and get a 10 second solve. Trying to get that sub-10 single :D

Lots and lots of slow turning is basically what you need to do to get to sub-15. It's all about lookahead, at this stage. Make sure you can track pieces (specifically, F2L pairs) with relative ease while doing any solve. If you can't do that right now (I can't), don't worry. Just do lots of slow turning to improve your lookahead. Whenever you slow turn, you should be at a speed so that you can lookahead really, really easily. A metronome should help you with this, though if you don't like using one, you could just turn at a constant speed and make sure you can lookahead perfectly. The interesting thing that you learn when you do this slow turning practice a ton is that you start to learn how certain F2L cases that are already set up change when you insert another F2L pair, for example. The thing that the masters (like Feliks and Mats) know by now is what happens to the other pieces on the cube when you do certain moves to insert F2L pairs and the like. I have started to notice these things. If you internalize and know how moves affect other pieces on the cube, then your F2L will be super fast because if you can track the pieces and you know what state they're going to be in, you know what case every pair that comes will be in, so you will have no gaps. Then, it's all about TPS, after that. Unfortunately, no one can really teach you how to lookahead or teach you how certain moves affect certain F2L cases. There's no spreadsheet for the latter, for example, since there would have to be absolutely tons of cases to learn for that. You just have to figure them out yourself. It'll happen, though. Just do lots of slow turning and lots of solves, and you will be on your way to sub-15. Good luck! ^_^

I'm assuming that when you say 6 second F2L, you mean not including the cross. In a speedsolve, you should be averaging about 12 by the time your pairs only are ~6 seconds, so you don't need to worry about getting there just yet. For ideal sub-anything splits, 2/3 F2L 1/3 LL is generally very close to what you should be aiming for, so 10 seconds for F2L and 5 for LL if you want sub-15. I average ~14 and although I don't know how fast just my pairs are, my F2L in total is usually around 8-9 seconds. However, my LL is slow for my speed (5-6 seconds), so as I said before 10/5 should be your ideal splits. For stuff about how to practise F2L, just read slinky's post.

I don't think he's including cross; I would also guess he inspects when he just times his pairs.

Your post is good, but I don't think I agree with this part. Turning at a constant speed is not a good idea; you should be turning a bit faster when you can see ahead to the next step. Like this. I had a longer explanation here, but this quote summarises what I said and was easier so I'll just post this instead:

something that Alex said helps with turning: turn fast when you know what your doing, and turn slowly when you're unsure.

I found doing this very helpful, and the metronome was just a distraction for me.

However, even after saying that, I do think that everyone learns differently and some people will prefer to use a metronome. I personally don't like the idea of it, but you can try it out if you want.

Thanks for than TDM. But I didnt understand that bold thing! And metronome is also a distraction for me so I just try to turn at a constant speed maximising look ahead. Sometimes I try to solve 2 f2l pairs blind but it is not always successful! And will you be kind enough to PM me your OLLs. I couldnt find your OLLs in algdb and you had posted it somewhere in forum but I cannot find it. Thanks for your help! :D
And yeah, what Alex said, I should implement it :)

Thanks for that :D I will implement it in my solves. Those were very helpful!

First bold part: when you say your F2L is near 6 seconds (or you want to get yours sub-6, so I'm assuming you're near 6 seconds), how do you time that?
Second bold part: the constant noise gets annoying, and I find myself unable to think. I'm doing a slow turning session at the moment, and I find if I start thinking about something else I often pause for around a second, whereas I don't pause at all when I can concentrate on the solve.
I don't try doing two pairs blind, but it could be a very useful exercise that should teach you more about how you're affecting the next pair. Imo, you should keep practising that until you can do it every time.
I don't know full OLL. You can find all the algs I use here (I just went through the ones I hadn't got on there and added them, so that page is now up to date, except OLL 24 where I use R U R D R' U' R D' R2, but that needs to be accepted first). I also have a few OLLCPs on there, but choose whichever alg you like for each case. I can't remember ever posting all the OLLs I know anywhere, but if it was a while ago I may have simply forgotten.

I will admit that that constant speed turning may not be for everyone. It is a great help for me and is the most effective for me because if I do what you said to do, which is just to turn faster when you know what the next step is going to be and you're tracking just fine, I don't really have the discipline to still be slow, so I end up going too fast and lose track of the pieces. This is why the metronome is great for discipline, for me. I am a musician, after all. I know that cyoubx doesn't like metronome either. However, some people, including me, like it, so I would recommend (to CriticalCubing) to try out whatever you think will work and test it.
 
I have a problem with my stickerless Dayan Zhanchi that causes the tensions to get looser without me adjusting them. As a consequence, i have to tighten the tensions every ten solves or so. Does anyone know how to fix it?

Did you overlube? I once got lube into the screw and it caused it to unwind.
 
When is it ok to bump a long dead thread?

I understand that if it's some big insightful post then it's ok, and if it's some short post like 'lol' then it's bad, but... The in betweeners, I really can't tell.
