Hey, I just switched from beginners to F2L like a month ago, along with doing advanced cross (still solve from white though). My problem is I solve the cross on an average of 11 seconds, even when I use my inspection time beforehand I just don't get the cross in the time I'd like. I know a lot of people solve it in like 2 seconds and I just look and wonder what my problem is. Can someone please give me some tips and tell me how they are able to do it so well? Thanks!
