I've been practicing pretty much 4x4x4 only recently, my main goal to be sub-1:15. I average about 1:25. I solve centers in ~20, edges in ~35, and 3x3x3 in ~30. Which of these 3 numbers would be the fastest to improve? I feel like my centers are slow, would it make a large difference to become color neutral? (I solve blue first, for crosses and centers).
I solve 3x3x3 in about 23 seconds on a normal cube. fridrich with 3-look LL
