LL-Skip in competition

[Lt-UnReaL]

The chances of a PLL or OLL skip seem pretty good yet it never happens for me?? A few weeks ago i had 2 PLL skips in a row and havent had it happen since then.

Same thing happens to me.

 

[Lofty]

I had a single OLL skip today but I don't even know if it counts because i used one of the like 5 zbf2l algs I know.. so I don't know the probability of the corners coming up oriented when you purposefully orient the edges other than that I may have had 1 pll skip in the past week or two...

 

[Karthik]

4! * 4! * 3^3 / 2 = 7776

4/7776 = 1/1944

Hmm...Also the probability of a OLL skip after a ZBF2L is 1/27.

 

[Johannes91]

Explanation: first 4! comes from EP, second 4! comes from CP, 3^3 comes from CO and it's divided by 2 because odd permutations are not possible.

If you multiply it by 8 (or 2^3), you get the probability for complete LL-skip (also works for OLL-skip, 27*8 = 216).

haha wow I have had over 6 PLL skips in the past two days! Not timed solves tho...

 

[GlowingSausage]

a week ago i had 4 pll and 2 oll skips in about 50. the 1 pll skip was my new rekord (13.97) and i got 25.xx nearly every solve with a skip that day. with sucks because i'm averaging about sub 21 to 20 :l
So what's the chance of getting 2 oll and 4 pll skips in 50 solves ?

 

[Goosly]

So what's the chance of getting 2 oll and 4 pll skips in 50 solves ?

(1/216)^2 * (215/216)^48 * 50!/(2! * 48!) * (1/72)^4 * (71/72)^46 * 48!/(4! * 44!)
Correct me if wrong.

EDIT: I didn't take in account that the OLL and PLL skips happened in different solves (so no LL skips). Fixed now.

Anybody had got a last layer skip in a oficial competition???

Milán Baticz austrian open 4x4 - 42.xy
István Kocza wc2011 3x3 - 14.xy
Gunnar Krig fungslangspark (or something similar) open 2009 7x7 - 7:xy
Tuan Nghia Duong french open 2010 3x3 - 9.31
and these are only the comps i've been to

 

[RyanReese09]

Dan Cohen has.

My 20 official OH single has LL skip. I couldn't turn fast for it.

ZZ^

Just got a PB in OH with a complete last layer skip.

Chances of this happening?
EDIT: Sorry i didnt look throught the thread. 1/72 * 1/216 = 1/15552

Read the thread sir.

Lasse Korbanka did an official 8.43 with LL skip at German Nationals 2011.
Avg5 was 15.32, lol.

 

[Sa967St]

I remember there was someone who averaged ~20 and got a sub10 LL skip single in his first competition. I can't find the video (he posted it here somewhere), and I only remember that the competition was somewhere in Europe last year.

Yep, that's the one I was thinking of.
