We’ve done some long runs where the calculator said it would work. Usually ok but that flat a field is likely pretty wet and not much help from surface drainage.
If you are on the bubble as to size, you could do the first 500 to 1000 ft of each run with 5 in. Relatively cheap insurance unless your tile boot only handles 4 in.
