I was searching some informations about OLL probabilities and found that on SpeedSolving forum from a British guy (Mark Rivers):
Here is a list of all the OLL shapes, ordered by the average number of moves they save compared to solving the same cases with 2-look OLL. Learning full OLL in this order is a good idea because the ones nearer the top will cut more time off your solves, on average.
10.00 Stealth
8.50 Squares
8.13 Dots (1/54)
7.50 T shapes
7.31 Small lightning bolts
6.67 P shapes
6.00 Kites
5.88 C shapes
5.58 L shapes
5.56 Knight moves
5.38 Fishes (excluding kites)
5.25 Big lightning bolts
4.25 H
4.13 I shapes
3.81 Dots (rare)
3.44 Awkward
2.63 W shapes
In fact, learning just the top 15 OLL algs delivers 42% of the total move savings of learning full OLL, so if you only want to learn some of it, those are the ones to go for.
If I learn OLL one day, I think I’ll memorize cases in this order, it’s smart.
The original post is here.
That’s a cool approach! I just printed some flash cards that I’ve been working through, this could be a good way to sequence them. I’ll need to figure out the lingo though(what the heck is a stealth) I’ll check the source to see if it is there.
Thanks!
If you don’t have an account on SpeedSolving forum but you’re curious…
You can download here pdf who made Mark Rivers:That’s interesting. I’ve known about half of the olls for years now. Maybe this will give me some motivation to learn a couple more.
Yes, it’s motivating when you can measure what you’ve earned.
What’s the stealth pattern?
I was wondering and this question was asked over there and he answered it:
Thank you for that list :)
Which ones are stealth and kites? Never heard those categories beforeStealth = OLL-28, H = OLL-57, the all corners oriented cases.
I separated out kites (OLL-9 & 10) and fishes (OLL-35 & 37) because although the wiki groups these together, they are distinctly different U patterns. Note that the kites can be solved by Sunes with M setup moves so are in the same “family” as the squares and small lightning bolts.
The dots are also separated into those with 1/54 probability and those with <1/54 probability; the move savings for the latter are weighted by their probability which is why they are so low in the list. Although rare, when one actually arises you still save a lot of moves (8-10) so they’re good to learn anyway.
