im learning full PLL and to be honest im getting mixed up ..i have learned 8 over the past month...and i still get mixed up...im practicing them and straight after...i can do them easy ..but the next day i have to get the charts out...there are only 1 or 2 that i know properly....those who say i learned full pll in 2 weeks are bluffing....there is just no way to remember if it starts with an R or an R; that quickly..recognition is easy ...but each Pll has so many moves and is similar to others...that you just need to learn them and then keep at it until you dont need your charts any more....its frustrating but worth it.
I suppose you think the people that can big-bld and multi-bld are fake as well? I personally learned my PLL in the 7 days of Spring break and can affirm it's possible. I wrote 3 or 4 algs on a piece of paper and practiced them on a nice 6 mile walk to XC practice. You should try to learn algs by their triggers (basically chunking) instead of the letters.
For example,
this, F', this, U', that
(RUR’)F’(RUR’)U’(R’FR2U’R’)
Also, try to follow the f2l pairs in the Pll. For example, in the PLL I just showed, you pull out an F2l pair then F' and pull out another pair, reinsert it a different way (called a sledgehammer) and then insert the first pair the same way you took it out.
Notice setup moves(for example, in R’U(RU’R’)(F’U’F)(RUR’)(FR’F’R)U’R the setup is R’U which is undone at the end), and cancellations
Once you know your alg, test it sometimes with your eyes closed to find your mistakes and to focus on its feel (since they will eventually become muscle memory).
Another thing that I do when I am learning algorithms is to repeat them right before I go to sleep. Then, I will practice them once I wake up. This helps me a lot and keeps me from forgetting yesterday’s progress.
Realize that a couple algs a day is possible since some suggest learning about 6 a day.
