Hi Mike, Yes, this has been thought about a little before I'm sure. It's quite possible to orient edges during the 3rd or even 2nd pair, but therein lie a couple of problems (at least problems I haven't worked out a strategy for yet!)
Firstly, because when coming to the 3rd pair, you have 2 unsolved pairs, it's quite difficult to spot exactly the orientation of the edges, and which edges if any need to be affected. Sometimes it's can look like you have no good edges, and so you might insert a pair R' F R F', but the situation was such that it didn't really help matters, because you may have flipped one edge while unflipping another. Also, if you try to flip edges during the 2nd pair, it gets increasingly hard to make sure to not undo in the 3rd pair what you have made good in the 2nd pair :) I would love to hear ideas on this.
