Do you get PLL skips too often?

[tikva]

Hello fellow speedsolvers!

I have been into cubing for 4.5 months, learning fridrich as my first method. I learned all the PLLs and OLLs before I could average 40. Now I average 25.

Please read my first post!

I had 13 PLL skips in last three days.
No idea how many cubes done total.

I know chance for a PLL skip is 1/72, considering all the possible permutations of the LL after OLL, but is this really so in practice? I mean, can the way of scrambling affect the PLL?

I don't use computer generated scrambles. I generally do Lw or Lw' and then some Us and D's, repeat, repeat, repeat... then cube rotation and repeat, repeat... then throw in some (R' F' R2 U')s. (yes, it's the R PLL finish... I can practice algorithms while scrambling )

I once got the exact same scramble (only 'shifted' in color) using my algorithm twice in a row. It was very strange since it was a pretty long scramble (my guess 40 moves). All the same F2L pairs, same OLL, same PLL...
So it's possible I learned to do a few scrambles from muscle memory and I don't notice the sameness of the scrambles, since they can be hours apart. So I can have a "PLL skip" scramble, ugly F2L scramble (a lot of these )...

Then there's also a tiny possibility of having solved ~(72 * 13 = 936) cubes in 3 days ...

Do the computer-generated scrambles really generate a random distribution after F2L + OLL or just F2L? How about just after applying the scrambles?

And for the end...
How much do you PLL skip?

Hey, 4-5 days ago I had 8 PLL skips out of 12 solves.

Scrambles can't affect the OLL/PLL. You should try to use a different hand scrambling technique, if you can get the same scramble twice in a row.

(although daniel lundwall is very good at this, and gives the impression of doing a truly random scramble, but yet can do the same scramble lots of times in a row, it's crazy!)

I think scrambling the cube by hand can sometimes affect whether there is a PLL skip or not (especially if you use a lot of the same patterns, like you do). But still, how you solve the cross, F2L, and OLL will change whether you have a PLL skip or not, assuming you use Fridrich. So it's not always the scrambling.

I have also scrambled the cube exactly the same before twice in a row as well. I find it funny because I happened to be doing the same exact scramble and happened to stop scrambling at the exact time.

I don't get them too much but I always get like 2 in 10 solves in practise and then 0 in competition so I just get them at the wrong time

 

[Escher]

skips have absolutely NOTHING to do with the scramble. literally, nada.
in fact, the only thing that affects OLL skipping is the last two or even last slots, and with PLL skips how you perform the OLL (i.e one look, two look, three look, different algs etc).

Edit

Erik, i lol'd at the last sentence.

3x3 WR anyone?



Edit 2

oops, i suppose they do joey...
still depends on what orientation you scramble on.

 

[joey]

Cross skips have stuff to do with the scramble

 

[Sa967St]

theres no such thing as too many pll skips

If you said 7, i would have believed you.

How unfair! You must always be behind your PLL-skipping competition

 

[PatrickJameson]

I get pll skips like 1/500 solves >_>. I wish i was as lucky as you guys...

 

[Escher]

i once got an avg of 5 where all the solves that counted for the avg were PLL skips.
funnily enough, of the two that were discounted, the one with the absolutely appalling last layer (a dot OLL i didnt know + an N perm) was sub 15, and the one with an anti-sune and an A perm was sup 20...

I think Erik is forgetting something, like, perhaps, the WR?

 

[CAT13]

I get one every 28374823 solves Not very often.

And Dene, why do you keep on switching your avatar?

 

[d4m4s74]

today I had the first pll skip in days
I do often have oll skips

That's an exaggeration. I think I get one about 1/72.

Dene had the same avatar for over 7 months, LukeMayn also had the same for a long time, then started to switch it a lot. Perhaps it's a New Zealand thing?

Maybe a little exaggeration

 

[Unknown.soul]

I rarely get (O/P)LL skips in computer-generated scrambles, more often with hand scrambles.

 

[ImNOTnoob]

I have gotten plenty of PLL skips, but for me its a 1/200 chance..
So far, i have 1 OLL skip and counting...

And NOT a single LL skip!!!!!

 

[*LukeMayn*]

^^ I'm the same >.< not one LL skip and I've almost been cubing for 10 months now >.>

EDIT: I take that back I got an LL skip on 4x4x4 with OLL and PLL parity O.o

 

[MTGjumper]

I had three PLL skips in three solves yesterday. Not like that would ever happen in competition.

And for the record, 3 LL skips, and 10 months of speedcubing. And only one was timed.
