anyone here use the petrus method, and if you do, what sort of times do you get?

i was looking at it last night and i learned the beginner method for it. i am not that good at it and it is taking me a long time to make the first two layers.

i am also wondering what advantages this method this has over the fridrich method (the one i am learning) except for the lack of algos to learn?

correct me if im wrong but doesnt the petrus method have signifigantly less moves and is often used in fewest moves competitions...?

Thanks

yer, 42.5 move average i think...correct me if im wrong

but those moves take a bit of working out at first

I think the biggest advantages are..

1. You aren't limited to 90 degrees turns (like with the cross)
2. Edges are already oriented when you finish F2L meaning you only need 7 OLL algs instead of 57.

Theres a couple of fine tuning things Lars and Clancy are working to try to trim even more time.

It's a really good method but I found myself wandering around the cube during F2L until I switched methods.

well once i have fully learned the fridrich, i might have a go of fully learning the petrus.

when i play about with the petrus now, it is from a puzzle angle. as in that it requires thinking for me to solve the F2L petrus style.

maybe i could apply it when i get my 4x4x4 :?:

I think that Fridrich method is more mechanical than Petrus method. It is good if you practice speed cubing but it is less funny.

I also want to learn Petrus method.

I've been doing Petrus for a couple of months I think. Fastest time yet is 1:16 (although that's artificial, my stickers are wearing down).

I like it better. With the petrus method you keep your focus on one spot of the cube for the two layers. rather than looking all round for the edges they are right there, I almost know all of the step 5+6 algs yay. it also divides the F2L up into 3 steps so you can look at one small part of your time and improve on that and only that. the only step I hate is 2 because I always make too many moves.

main point

layer by layer methods use way too many moves. because the first layer works againsed you. you must constantly take it aprt and put it back together. what a pain. in methods like the fridich you need a method for every edge. not with petrus.

Petrus method has many advantages for using less moves but they're hard to do while speedsolving.

Comparing after the first step of both CFOP and Petrus is fair, 4 pieces solved.

With the Petrus 2x2x2 box you can still turn 3 different slices without disturbing what you've built which is great for finding shortcuts but it's more to look at.

With the Cross, you can turn only 1 slice (LL) without disturbing what you've built, it narrows down the choices you have to make while speedsolving which is a huge plus. Very many CE pairings are able to be done using only 2 slices (2 gen) which is very fast.

I figured out the CE pairing techniques I use on my own, I never studied someone elses F2L CFOP algs. I would be so much faster if I could just focus harder at looking ahead.

no. using the petrus method going fast I don't need to turn the cube all the way around to find an edge. and you can see all three sides at the same time if you hold it right. you just need quick reactions.

some may argue it is the same with fridrich's

I just find that I get the two layers quicker this way. I get F2L in about 16 or 17 seconds. thats pretty slow though for that method I usetoo may moves on steps 3a and 3b.

I had never solved a Rubik's cube until about a week ago, when I learned the Petrus Method. My average is 2:10... At first it took me 20 minutes each solve, then I quickly went down to 5 and now I am almost at 2. I do not have much experience, but I picked up the Petrus method very quickly, and now I am almost able to recognize what to do very quickly, rather than studying the cube for 5 or 6 seconds.

In other words, the Petrus method has worked miracles for me.

Keep it up. I got under a minute average in a month. I've been going on and off since october and I'm down to 40 second average. Fridrich method though.

im just wondering, why is it necessary to use swear words in your member name. I don't mean to pick on you smart***, but i dont see why it needs to be done. Save your swearing for somewhere other than here.

yeah I just finished learning step 5+6. I figured I'd learn that before 6+7 becuase it occures a lot more often. The trick with learning them is not to look at all of them at once. do one catagory at a time. then learn another. After a while they should pop into your head when you see it on the cube.

I can get the last layer in about 6 or seven seconds. I need to use less moves for the first two layers.

Lars site is the ultimate for beginners. The Java cubes and layout is unmatched and in a class by its self for learning.

I hate to say it because I know Lars personally and because he's one heck of a great man but I think CFOP and Roux have an edge up on him for a speedsolving method.

His approach is great because of the LL edge algs are eliminated, leaving 7 LL orient(down from 57) algs but I think it may take 2 brains and 4 eyes to take full advantage of it for speedsolving. Fewest moves is another story though, Petrus Pwnz!

Don't count him out though, although he's older than he's ever been, he hasn't given up on perfecting his method. Believe me, there's more to come.

I wonder how fast he would be if he jammed on CFOP for 2 weeks though. I saw him get some 20somethings solving Roux, the same day he learned it.

i think it is lars who said that he himself cannot get the full potential out of his method.....or maybe that was roux?

Yeah, Roux is very fast with the petrus method.I hit 15's alot during averages if i look far enough ahead and don't make mistakes.Roux's new method is also incredibly fast if you have keen recognition.

The trick to his method is learning the fastest way to put the blocks together. When I am trying for less moves, I can get the F2L in about 28 or so moves.

Point taken... I should have thought twice about it.

Is there any proven way to take a couple of seconds off your time? I am not looking to jump from 2 minutes to 25 seconds, I am just curious as to whether or not something like cubesmith.com's textured tiles are worth it, as well as anything else that might help. (I am talking like 10 seconds, or even just mproved grip.)

Why not look to jump to 25 sec from 2 min, that's a very achieveable goal.

The key to getting faster isn't the stickers, it's just practicing over and over until all the steps you need(to solve) are so ingrained in your brain that you don't have to think, just react to whatever situation presents its self. That way you can look for the next step while you're doing the step you are on.
You can get under a minute using pretty much any method, but some are better than others for different people.

If you keep at it, you might be surprised at how big chunks of your solving time will melt into oblivion.

The two biggest time wasters when you are over 1 minute are not looking ahead and making mistakes.

I noticed a sudden jump from about a minute 20 to 50-1:00. it was really weird. I wasn't trying harder or anything I just got faster. the same thing happaned again this time for 30s to 20s.

I think I used to waste time trying to orientate to corners. I only knew one alg for it. I used to use 70-120 moves.
