Week 3 started, see main post for updates. Plus, @Tao Yu and @2180161, any advice for expanding and lookahead? If I go slowly, my movecount drops a lot, but it takes forever for me to find the pieces.
Go for the go slowly one and keep the same D colour. Also, make sure that the final 2x2x3 is built in the back. That's pretty key.

I don't use Petrus, but for me, I was just doing some untimed solves and then *snap* lookahead=amazing. Obviously not amazing to a top cuber level, but I went from very very little to wayyyyy more.

I feel like it would be VERY hard to achieve even sub 12 with Petrus. Other methods have much more potential and have many more resources. There are hardly any videos on Petrus but quite a few more for CFOP being the most popular. Then Roux being the second most popular has a decent amount of videos. And then ZZ being Third has a few videos on it. I feel like you should switch to ZZ or Roux because there are still this block building elements to them so you would not be horrible using them at the start.
Just because there aren't videos on something doesn't mean it can't be done. I don't feel like the point of his "experiment" is to get fast, but to get fast with Petrus.

Haven't read the whole thread yet, but I wanna throw a few tips here that I think will help for OP, or anyone else who genuinely wants to put Petrus back on the map ;)

First, you should do your best to avoid focusing *too* much on the method Petrus itself, and instead just focus on getting better period (using Petrus obviously). This could include things like looking into your fingertricks and how you're performing certain triggers and sequences. Regardless of what method you use, improving your fingertricks will always be fundamental and paramount to getting faster

For example, if you know how to do all of the steps of Petrus efficiently (or ANY method for that matter) but your fingertricks are lacking, then your speed and ability to solve quickly will be lacking period

Secondly, one of the unfortunate truths is that essentially all of the useful info content that exists for getting better at cubing is very much CFOP focused. There's some good Roux stuff out there too, and maybe a handful of nice ZZ focused videos. Still, for the most part, you're going to learn the most from content that isn't really intended for the method you're using

One quick idea that comes to mind is Cross + first pair in inspection for CFOP being a big deal, and something of a sticking point for cubers who haven't taken the time to practice *pushing* their inspection abilities by taking away the 15 seconds of inspection element when practicing at home. There's no reason why you can't apply the general logic of this to Petrus

Let's say currently you can only plan the 2x2x2 block half the time. Working towards being able to see it every time as a mini goal would be very helpful! From there, you could even take it up a notch by working on also seeing a corner edge pair that goes with the block on top of that. Making sure that the blocks aren't in the U layer when you solve them might be another thing you could work on (this would be relating the concept of "cross on bottom" to Petrus, since you'll want the first two layers to stay on bottom since LL is on U)

Again, there's a chance that I might be repeating advice already given ITT (cbf reading all of it lol), but hopefully this steers you in the right direction :)

Do you guys think that sub 20 by January 19th is reasonable? Because I have a comp there, and I would like to make it to the semifinal at least, and maybe the final. (Based on previous competitions and their results). Sub 27 would put me around 72nd place, whereas currently the standards for the semifinal is top 64.

where do you live I never knew there were comps where you could make finals with a 20second average. also 20seconds Is easily achievable by january

Nah, not finals with 20 secs. I just want to achieve that. For semifinals, it’s around sub 22, finals sub 16. Note this is from 2018. I live in Hampshire, Portsmouth/Southampton/Isle of Wight area.
K thanks for the answer.

Speaking of fingertricks and to come back to zbll once more, I would recommend that once you know coll, you could try to learn a little bit of 2GLL. Besides it being a subset of zbll, the algs are mostly really easy. Mainly T, U or L.
Main reason for now is fingertricks, especially left hand stuff like U2 double flicks and also left index push for U. Learning 2GLL has greatly improved those moves for me. I used to regrip to do antisune with a right hand double U. Trying to get 2GLL to be fast forced me to practice the lefty double flick and now I do antisune from homegrip. Same applies to left index U push. I‘ve been using it before but learning 2GLL made me much better at it :)

K I’ve learnt the T COLLs, recog is pretty bad though, and one alg I just can’t do fast yet. I haven’t been working too much on seeing my 2x2x2 in inspection, I find the piece, plan out the first few moves. 2x2x3 is improving slowly, still pretty bad, but another week and I think I’ll be good. Once I finish that off, I‘m going to work on EO recognition, learn all the 4 and 6 bad edges cases, and also improve on finger tricks. I’m literally just working through each step one by one. After THAT, I’ll probably put some work into inspecting my first block and a bit of the second. And some ZBLLs.
