I believe the guide says something like "...and expand in a total of 6 seconds..." so I mean the expansion should only be 2 seconds. The reason being is you should at that speed, you should be able to one-look your 2c2c2 as it is very few moves (I do it in about 5 or 6 on average) so while you don't have a lot of time to look ahead during the solve, but if you're efficient, you can see more in inspection.
... I'll need a lot of work in the 2x2x3 area. Also, can you give me some of your splits, so I can look at how much better one area of my solve is than others?

Edit: Are the Sune and Anti-Sune COLLs worth it?

they aren't really worth it on their own but their ZBLL counterparts are worth it, so might as well learn the COLLs to get good at recog and pick up a few algs.

In the short term no unless your execution of sune and anti are bad. But by learning them you learn the fundamental recognition for their ZBLL which are worth using. Plus you’ll be able to have 1/12 for each corner permutation set done for their ZBLL and a small chance for skips

This was just an AO5 I did like as soon as I woke up and I'm also very sick, and out of practice so these probably aren't the best splits, but this is about where mine are. The splits are 1/2/3/4/5 = 2x2/3x2x2/EO/F2L/LL.
Also no clue why this looks bolded on my end

Update: Know 4 Sune COLLs now, and attempting to break sub 8 moves consistently.

Edit: Developed new and improved way of building 2x2x2, need to practise it. Plus, I'm going to work on memorising some common cases (e.g. pair formed, edge in place, partial cross, etc) so I have an archive of different positions by the end of the week.

If you do want to use petrus using 2 look last layeris better than COLL PLL. Use OLL PLL for the time being with the goal to know full ZBLL (but that is long down the road). You have an advantage with ZBLL compared to CFOP. In CFOP a ZBLL comes up 1 in 8 solves.

Please don't listen to tx789, and I mean that in the nicest way possible. COLL/EPLL is leagues better than OLL/PLL especially in methods with edges oriented such as Petrus or ZZ. Similarly, learning COLL/EPLL will be your best bet to finishing ZBLL as fast as possible, assuming that is your end goal as ZBLL uses a recognition method that is essentially COLL and then 2 other pieces (typically).

Any reasons why OLL/PLL is better? If I use COLL, I have 4 algs to pick from at the end, and a higher chance of PLL skip, so why not? Also, it makes for a good transition into zbll.

There are no reasons. He seems to not know what he is talking about. It will probably have something to do with certain COLL's being slower than the OLL, and while that may be true, the skip chance, less resulting algs as well as them being faster, far outweighs those maybe 5 algs.

Ok well I just got done doing something, I pick my cube up and decide to do a Petrus solve. Ok normal sub 40 petruser here and then out of no where I get a 18. WhAt Is ThIs?!?!

Could someone post a few walkthroughs? I can't find any one YouTube, and it would help my understanding of how it all works
Check out 2190161 s link in the last page. Scroll down for my example solves. May not be the best though, lol, and I never finished it.

@2180161 can you give me an example solve please? Hopefully I can spot some things that I should be doing. Also, I have no idea how advanced Petrus (if it exists) works.

Gan 356 X you can look at this as well.

^ I was a tiny bit surprised to see there aren’t any solves tagged as Petrus on cubesolv.es (although there are likely some tucked away in there somewhere).
There are a couple of old threads on here (sub-20 with 20 methods, sub-10 with 10) which I know had Petrus solves reconstructed by @Brest which might be of interest?
