Optimal Pyraminx Method?

[RyanO]

hmm is Oka/WO necessary for sub-5? I use LBL and I get sub-6 sometimes, and tips take me like 1.5 secs >.>

any tip is welcome

Are you asking about sub 5 singles or averages? I use LBL and I get sub 5 singles quite regularly. Only 3 people have official sub 5 averages, so that is going to be very hard with any method.

Haha.. I see my friend playing pyraminx, and he's too dumb to finished it, just like me

1) Oka/WO is not necessary at all to get sub 5.. the 3rd and 4th place on the WR list average uses Polish V, Simon Westlund uses LBL the same does Piotr Kozka

2) ehhm... don't pause xD just solve

Ok, I have managed to get my move count way down in the last day, because I have started making my V using oka style (kinda, 2 edges on a corner, then orient two other corners for the V). I'm getting quite a few sub 10 movecounts (excluding tips) and my V is way more optimal now. I used to orient 3 corners, then insert two edges into it, to make the V lbl style. Odder, when you use Polish V, how do you usually make your V?

4, 5, 5, 6, (1), 6, 3, 4, 5, 5, (8), 5 = 4.80 average for V. I don't know all cases so I couldn't do full solve really, but http://www.mzrg.com/rubik/solving/pyraminx/index.html says part two has a 6.71 average move count, so my solve average (a bit rough because I might have had a higher average move count for second part, or lower) was 11.51.

my brother thinks he can solve a pyraminx because i gave him a case with like 3 moves

1) I don't use polish V, and if I do I solve the V VERY close to optimal... (MAXIMUM 2 moves more than optimal...)

2) when I do something like the polish V I usually do some actually orient and permute one of the edges (optimal+1-3 moves... which is pretty nice =) )

my brother thinks he can solve a pyraminx because i gave him a case with like 3 moves

this was relevant because ...?

Can you give a few examples? I don't really understand. Are you basically doing it completely intuitive, with no real structure? Just finding the fastest V you can see, but not following an order of making it? I don't understand >_>

Wow, I see why I'm slower than you. I really need to start making my V better.

should be working now

EDIT: Bruno found B' L' R' for scramble 3 :/ so obvious solution lol

Two of them are optimal!
My method is basically Oka, but a little different in the first step.

Keep in mind these are my speed solve move counts and not pyra fmc

 

[WoowyBaby]

If anyone’s wondering, the average movecount for optimal solves is 7.7955 moves (plus 2.666.. incl tips).
If anyone solves it (excl tips) in under 12 moves on average then that would be very efficient. I take like 18-20 moves on average during solves lol.
