Working on Step 4 this week, my 2 gen blockbuilding skills leave something to be desired. I should go through my F2L algs and lookahead from EO as well to increase TPS potential.

Speedsolve reconstruction. Any advice? (Apart from stuff like cancellations)

My advice: don't get a DNF ;)
 
If you do them the same then it's Petrus-W :)

For example, take this setup. For Petrus, EO is solved, and you can do a y' and then solve F2L with R and U. For Petrus-W(ZZ EO), this is unsolved EO and you need to finish EO before doing L2P with RUL
petrus W is objectively worse

Nice improvement! My stats are not improving fast at all compared to you lol.

He probably spends a lot more time cubing; you have 659 solves in your current session, mukerflap has 2848. Still great improvement for both of you!
 
Lets try this again, and hopefully get it right, lol
Speedsolve reconstruction (2nd try with actual scramble, pretty good)

Pretty nice solve, I actually knew that ZBLL for reference. 49STM, so around 3 TPS.

WTH NO. L‘ U L in EO was meant to be L‘ U’ L FML.
Corrected. Happy now lol?

Ok, better. I'm analyzing with my extreme knowledge that happens to be less than yours right now.

Ok, as far as I can tell the 2x2x2-EO was good. For F2L I would've done

y' R U R U2 R' U' R U2 R U2 R' U2 R U' R'

And that leads to an easy COLL->U-Perm

Hey guys, I've been cubing for half a year now and use the Petrus Method to achieve sub 50 solves. I'm not sure why I'm posting this except that the admin told me, but I'm also going to turn this into a tips thread. So...any useful tips????

Edit: I'll make it clearer that I only started seriously cubing in May. I learnt the LBL over the course of a few months round the end of 2018, then lost interest for a while. I picked cubing back up when my brother challenged me to a cubing race (I got a sub 2 min).
Been a long time... Improved by over 30 seconds :)
I’ve long surpassed my goal put in the intro to be sub 30 with Petrus :)
