Ok, this is a long question and will take a lot to explain, but the answer should be short and that is why it is in the one answer question thread.
So I just started learning how to blind solve about a month ago and I am almost ready to try my first solve but there is one problem that I don't understand with the edges using M2. First, let me try to picture this in your mind. The bumper sticker (the bottom of the FD edge) has to go into the A position in the M slice (or some other letter if we are using different letter schemes) all the videos I've watched and articles I've read tell me to simple do M2, and that puts it into the A position after your next target swap. But the thing I don't understand is, what if after the do M2 (and put the bumper sticker into the A Position) the next sticker that cycles into the bumper position, ALSO needs to go into the A position using M2 (after the centers have been swapped.) The same thing applies when it needs to go the the sticker behind the A position, what happens if after you execute the algorithm to get it behind A, the NEXT sticker also needs to go behind A (again after the centers have been swapped using M2.)
Any help would be great on this because this is the last thing I need to know before I start blindsolving.
P.S. I promise this long post was my last option because I couldn't find any good tutorials on what to do
