I dunno, in my pool, with the way all the returns work together, it's more important to get all the surface water moving toward the skimmer. This means that the return closest to the skimmer (not counting the venture return) is actually kinda aiming toward the skimmer. If I turned it the other way, it would be shooting against all the water that was heading towards the skimmer as a result of all the other returns. I don't want a total dead zone right in front of the skimmer. Better to have some clean water go back in and take the other water with it.
