I agree with you, there are too many variables.

Every area of a city is different same goes for every subdivision, every yard.
Granted, toss in muni pressure constraints, infrastructure age and condition, public and private wells and our diminishing auqafers.

Sometimes you need overlapping coverage sometimes head to head is too much.
I was taught that a system with 10-20% overlap of the head with the valve throttled 1/2 turn and the heads unrestricted would allow for future performance issues caused by dwindling supply and pressure. The heads throw is then adjvsted head to head.

Depends on the soil, slope and maybe even the neighbors way of watering.
Again, i am not in disagreement
