I am sorry. That should be 5 x 1- 1/2" holes for overflow and 4, returns.Where are the 7 1-1/2” holes exactly? (I see 2-1/2” and 1-3/4”, and 5 holes in the overflow - not 7, and 4 additional return holes in the side)
It was recommended to do more than 3 as the coast to coast is 7ft across.I do not have a setup with more then 3 drains.
Is the amount of flow you are targeting more then 1 1/2 drain can handle in full siphon?

Thanks for the disclaimer and advice. I am leaning towards this as well!Ok
I was just stating that I do not have one so no experience just theory
I would probably try to full siphon, two trickle and one emergency or switch the trickle and emergency number.
I would have one full siphon fixed about half of your target flow and the other one adjustable.
