By setting up cases i mean setting up the pairs before insertion.This is where most cube rotations are done at iinm. Try set up the pairs at different angle and yes slotting at different angles as well.Will save a lot of time

Heck, i also do cube rotations a lot hence my slow times

Now trying to learn F2L algos and OLL/PLL cases

Hmm, sounds logical.....
Although I'm using intuitive F2L, but I've kinda created my own algorithms, so it's implemented to my muscles, lol......
I'm sure some of them are not minimal in moves, but at least I execute them smoothly....

So while I'm inserting a pair, I'm already looking for the next....

Hmm, my skills on setting up the cross is still weak as well.....those strong cubers are able to plan the moves for the cross, and even the 1st pair if possible, during the 15sec inspection.....

And I just able to plan to set up 2 or 3 edge pieces of the cross during inspection, or set up whole thing if the cross was easy....

For easier look ahead for setting up pairs, most of the cubers will do the cross on the bottom face as well, so while setting up the cross, they can already looking for pair pieces on top angle.....
This is even tougher to do, lol.......

How bout this?
