Can someone give me the short answer? Would it be more efficient(least costly to run) with the Intelliflo to have the slowest GPM to turn over 1x per day AND have the largest pipe with minimum 90's to have the lowest pressure/head???

I am having a pool built and using the Intelliflo and my builder thinks I am too concerned with the over use of 90's and pipe size. He indicates in the past--with the regular Whisperflo he has to use eyeballs to get the head up.
