I noticed a unique part of my solving and that is that when my cross f2l transition is smooth i avg about 23sec and when it goes rough I avg around 28 sec. I know this is a look ahead issue as well as my cross not being wonderful (3-4 sec), but my question is how do I track the first pair? Is this done as the cross is being formed, during inspection or do you just deal with the cards your delt when you get to f2l trying to locate the pieces as quickly as possible?
