Practicing F2L is really making me more consistent around the 30s mark:

And memorized some interesting algs today (ignore the BR fingertrick; OreKehStrah taught me a better way):

Apparently the FL alg is a commutator, but I have to do more research on what that means (or reply below if you can teach me what it is):

A commutator is an alg which is of the form A B A' B'
let me show what that means through an example:
so, your F2L 33 alg is R' D R U' R' D' R U(adding the U in the end because it'll be easier for you to understand)
here, you can split this into (R' D R) (U') (R' D' R) (U)
you see that you're doing one set of moves, then another set of moves, then undoing the first set of moves that you did, then undoing the second set of moves that you did.

if you still don't understand, watch this
