Getting up to cruising speed in a short time and avoiding unrequired stops will improve MPG a little. The trick now is for you to find the optimum acceleration and cruising points - the ones that bring you the best return.
I'm in the same boat. I've tried gentle acceleration and short shifting. It works in town but I'm going to try higher RPMs and maintaining progress on the Edinburgh bypass (think tiny freeway) and see if that improves there. It will take a few runs to find the best approach or to disprove this as an idea.
Swerving in Traffic ? Hmmm
Although I think you mean lane changing a lot to maintain progress.
