Inaccurate Weather Readings

Thank you
I don’t know my water flow amount, but I can get water catchers to find out.

I only have 4 zones, two of which a fairly large.

Zone 1 has approximately 16 sprinklers
Zone 2 has approximately 11 or so sprinklers for the perimeter of the home.
Zone 3 has 4
Zone 4 has 4
