Sorry if this doesn’t belong here, couldn’t find a thread for this.
So I average about 23-25 sec and want to get sub 20 consistently. My Pb is 14 sec. I know 2 look oll and full pll ( except the g perms and the nb perm) with intermediate f2l. I think I need to work on f2l, sometimes I’m faster then others. What should I do?
