Someone's a beast. ;) If you stackmat a 4/4 on video, I think I'll cry.

Is that a challenge? ;)
 
I just did a 9:53.44 on tape. But it was a 3/4 :mad: First cube had two flipped edges :(

I used scrambles 5 through 8 from this week's forum competition. They were pretty hard :(
 
My first 4x4x4 BLD on Stackmat:
09:15.86, 03:40 memo.
PB by 32 seconds.

But with Maarten's 6:57.73, mine just looks so slow. :(
 
You guys just get so fast so soon. I'm really impressed by both of you, Chuck and Maarten. Chuck, if you improve as quickly as Maarten did, you'll probably be sub-7 in a few more weeks.

Maarten, I've beaten that only once. By only a few seconds. It's probably safe to say that based on improvement trajectories, you're already better than me. Congratulations - hopefully someday I'll catch up to you again. :)
 
My first attempt at optimizing center orientation on a 5x5x5 (first scramble in the weekly competition): 16:29.64 (8:37)!!!

I admit I was hoping for better speed, but I was also very nervous - I really didn't want to miss it, and I was probably overly careful on the memorization for that reason. I was shaking as if I were at a competition. :)

I was excited when I first looked at the scramble, because the normal orientation only had 4 or 5 center pieces solved, and there was a row of orange pieces just begging to be reoriented. I think it was something like 14 centers solved after orientation, and a 4-move commutator to fix centers.

Very cool. I'll definitely be trying this more often. :D :D :D

Congrats Mike! My first try with this technique on a 5x5x5 was a disaster (see the Failures thread), but I'm not going to give up! You must have found a better orientation than I did! I did the same scramble, but only had 10 centers solved after my orientation :p ;)

Will try again soon on the second scramble. Congrats on your success!

First successful 5x5x5 BLD solve using center optimization! 2nd solve for the weekly competition. The time was not fast for me, 20:51.20, but it was a success! It took 15 seconds to orient the cube, and after doing so I had 14 centers solved (saving me about 3 images). I had a huge memory recall delay during x-centers, probably because I was so nervous to keep everything straight from center orientation, parity, plus I was doing a pickup cycle to skip the forgotten stuff and come back :p

Can't wait until this becomes second nature, surely this is the path for me to finally getting a sub-10 5x5x5 BLD! :D :D And again congrats to Mike for schooling me on center optimization right out of the gate! Mike, now I need to catch up to your speed!

--edit--
12:52.55 on the third scramble for this week's competition using center optimization with the initial orientation! After the orientation I had 11 centers solved, optimizing centers on odd cubes ftw!

Ok Mike, let the leap frogging commence Sir ;)

Impressed and challenged by Chester, I decided to try it by myself:
multiBLD 4/4 in 12:36 (6:55).
Lets face it: multiBLD is becoming a speed event thanks to the growing competition.

Chris, Mike and others as well: I will join the fun soon, I am learning commutators.

Heh. I know you're out of my league. I just got lucky with the first solve. I think your average on 5x5x5 BLD is now about 2 minutes faster than mine. Which is great from my perspective, since at least I've really closed the gap - I remember when it was about 30 minutes. :)

Oh, and I double-checked the first scramble just to be sure, and I was right - it was 4 centers solved without reorienting, and 14 centers solved with reorienting. I did x' y' to reorient and get 14 centers solved. It was an outrageously beneficial scramble for the new technique. Most scrambles aren't that good for it. When I was experimenting this weekend to practice, I was seeing an average of 7 or 8 centers solved without reorienting, and 11 or 12 after reorienting, which is a surprisingly small amount of benefit on average. Still, if it only costs 7 or 8 seconds to check, I suspect it's worth trying, since it really is pretty easy to do.

Chris, on that first scramble, I really do wonder if you just applied everything as either X centers or + centers, meaning for instance that you first solved all the X centers, then applied all of your + center memorization as if they were X centers too. I've really tried, but I can't think of anything else that would explain it.

And Micael, nice try on the multi. You and Chester and Chuck are just way too fast for me. I seem to have hit a brick wall on improving my multi speed - I'm afraid I won't be able to keep up anymore - I just don't know what else to do to improve. I am going to try experimenting with doing less memory refreshing - somehow I need to find a way to make that work.

I don't think it is, honestly.

It's just me. I don't think I can do any more than 5 cubes because of my pathetic memo system - what system? :p And so I just go for speed for personal satisfaction. In my opinion, anything under 5/5 isn't really a feat no matter how fast it is, just because it isn't THAT hard to try it over and over again, rushing memo everytime, until you get one success. But that's just me.

I wish I was one of those guys who could do 10/10 :rolleyes: I just don't have that sort of memory.
