[Mike Hughey]

I've gone backwards recently and not practised multi at all. Would be good if you get ahead of me and give me a new target to motivate me

It's just a crazy goal for me to shoot for. I probably have very little chance of making it - I'm sure 15 will be a stretch for me. But it would be fun to at least try. I'll give it a couple of attempts this week leading up to it, just to see how it goes. I'll only try it if it seems at least somewhat possible.

(D’ Rw2 U) M2 (U’ Rw2 D)

I can’t recall who the video was from... but he also discussed how to plan the memo to purposefully place the UB and UL pieces in reverse location so you can avoid doing the parity alg all together... I fully understood the concept, but it was a bit too advanced for me at this point. But it’s something I’ll definitely keep in mind when I’m comfortable with M2 and ready to improve my skills further

I guess the video is from Josh Weimer. His advanced M2 video is quite good (total of 3 videos).

UB/UL swap is the best way for 3BLD but for multi, it depends how you do it, so better getting used to at least one parity alg. It also works for bid BLDs (just swapping can't take care of the whole parity for big BLDs, not easy).

Yep. Josh.... that’s the video I watched.

I don't use it in MBLD as I memo edges first but I do in 4BLD and 5BLD (wings and midges get swapped).

That means you memo corner first / execute corner last for big cubes as well?

UB/UL swap is the best way for 3BLD

I'm not convinced. If there are N+1 targets without swap, where N is even, you will have either N or N+2 if you swap instead. Intuitively the odds would be 50/50 and I'm sure I've seen that confirmed mathematically somewhere. So the average is still N+1 targets.

If you use vanilla M2, edge parity costs about the same as an edge target, so swapping hasn't bought you much on average. Best case is that your standard deviation goes up and you get a few slightly faster singles as well as a few slower ones, which is arguably worthwhile for an event ranked by single. That assumes it doesn't cost you any extra thinking time to swap.

If you're a faster solver and use full edge comms, you're more likely to see an advantage on average because the cost of parity is close to the cost of a full comm (pair).

IMHO, apart from the chance of slightly faster singles, the biggest advantage of swapping is that you can turn it to your advantage when you spot flipped or solved pieces in the UB or UL positions. Turning a flipped piece into a regular target to avoid a flip alg is worth more than avoiding a parity alg. Example: I have parity and plan to swap UL and UB. When tracing I spot that UB is already in the UL position but flipped. So I change my mind and don't swap, doing the parity alg instead, effectively trading a flip alg for a parity alg.

Also, for 5BLD swapping the UB and UL wings during memo when you have midge parity is a significant saving compared to swapping those wings with an alg.

Interesting analysis.
In general, I'm assuming advanced M2 which means most of targets solved in pair. For people who would do the swap, likely moving to advanced M2 or full 3 style. So, it's better (=faster).

OP edge or basic M2 (vanilla M2, lol, love it!), Yes, agree to your point.

Yes, advanced M2 is somewhere in between, although I wouldn't say most targets are solved in pairs. Maybe half, on a good solve, and advanced M2 "comms" are generally not as optimal as full 3-style anyway.

I kind of think of UB/UL swap on 3BLD as similar to colour neutrality on 3x3. It's fairly clear there's some small advantage, but you have to be pretty fast already to reap that benefit, very comfortable with the technique to avoid even minor hesitation that simply wipes out the benefit, and you have to switch as early as possible to get so comfortable with it.

I've been practising with it for a few months now. My tracing is about the same speed either way, but swapping still seems to make me slower while solving, so I don't yet use it in timed sessions. It's in the bucket of things like E and S comms, 3-twists and floating buffers that I use regularly untimed but are not yet ready for use in timed sessions.

The bucket of things not used it timed solves.... I like that.

Right now, using OP edges, if I have a parity, I don’t use the R-perm. I could, but somehow I fumble it and have just kept with the UL-UB-UL three target cycle. So... if I swap them in memo/execution, even if I add a target, I’m still saving two targets which are solved with t-perms.

I’m a LONG way from trying to milk a couple seconds... I’m still at a point where regular practice can same me minutes. I’m still playing around and seeing what works.

I did it once earlier today and it didn’t slow my memo down at all. I just placed them in the swapped location mentally and then executed as normal for an even number of targets. I wasn’t timing, so can’t say if there was really an impact. However, I didn’t have any struggle doing the swap on the fly as I traced out my memo.

I had no idea, when I first started learning blind, how many nuances and differences there could possibly be....

True, it's the same mean, but not the same standard deviation. When using a parity alg you'll always have to solve exactly n+1 targets, whereas if you swap UB and UL 50% of the time you'll solve n, 50% of the time you'll solve n+2.

Assuming you're using comms, n targets will require n/2 algs, and n+2 targets will require (n/2)+1 for an average of n/2 + 1/2 algs per solve. With a parity alg, you'll always need n/2 + 2 algs per solve (n/2 for the first n targets, one more for the last target, and one more for parity).

So if you choose the parity alg over swapping, not only are you eliminating the possibility of doing 2 less algs on half your solves, on average you're executing 1.5 more algs!

Yeah agreed; I think we are making the same point, which is that the potential benefit is small until you are using full edge comms. Most people here are M2.

 

[newtonbase]

That means you memo corner first / execute corner last for big cubes as well?

Yes. I'd do it on MBLD too if I could find a safe way of organising it in my rooms.

3BLD to start the day.... 3:51! 1:56/1:54

Now, I just need to get that without a string of 7 DNFs leading into it. LOL

 

[adimare]

Yeah agreed; I think we are making the same point, which is that the potential benefit is small until you are using full edge comms. Most people here are M2.

But even with M2, in the worst case scenario of swapping you'll have to perform n+2 algs, which is the same amount of algs you'll have to perform on every solve if you use the parity alg approach (n+1 targets plus parity), but on 50% of your solves you'll only need n algs.

So with one approach you'll have to perform n+1 algs on average, with the other n+2. While it's true that your std deviation will go up, what you said afterwards doesn't hold up. You're not expected to get some faster times and some slower times compared to what you'd get with the parity alg. ~50% of the times you should get faster times (n targets, n algs vs n+1 targets, n+2 algs), and the rest you should get comparable times to what you'd get using a parity alg (n+2 targets, n+2 algs vs n+1 targets, n+2 algs).

Holy crap! Just doing some 3x3... my PB "was" 16.41 from last month. That was a HUGE improvement over my previous 17.xx.... Then, this happened,

15.71 single. I'm honestly very excited.

Okay, CubingUSA Great Lakes Championship is just a week away, and as usual I didn't have enough time to practice like I wanted to and I've gotten terribly rusty at most things. I'm going to start trying to get back in shape for ordinary 3x3x3 BLD; let's see how I do. My first 20, done today:
14/20
session mean: 1:53.70
best: 1:21.23

I sure hope I can improve some before then; that was awful.

I'll also try a couple of multis between now and then; I hope I feel confident enough by then to go for another PB. I'd love to try for 15 and have one last long shot at getting ahead of Mark on the oldies list one last time before he puts it out of my reach forever.

I'm bummed to have a conflict come up and it's looking bleak for me to make it next weekend, was really looking forward to meeting you and picking your brain. Good luck getting the rust off in time.

You're threatening my 3bld PB and now you've ducked my 3x3 single! Good couple of days.

LOL... Yeah... It's been a good couple days. I updated the old-guys spreadsheet and noticed that I got in just under your posted PB single

It comes in fits and spurts. But, when I hit a lucky streak like right now I just know that is in the realm of the possible for me.

Yes you're right. Maybe I should put in more effort on it.
