Thanks Andy, 90 degrees is the answer, I will do that and make up for any
lawn not being watered with pop ups and set them to whatever degrees I need.

I assume the reason for the "overwatering" is the fact that
the 180 degree sprinklers in each side OVERLAP, and NOT
because of pipe size or pressure drop...

Why not consider four 90 degree heads, all in the center,
facing each side.?"??? That should get rid of the overlap and use
the same amount of water......

Just an idea...
