If you are in Sumter County, you are only allowed to water twice a week, per the Southwest Florida Water Management District ( Welcome to the Southwest Florida Water Management District Home Page). If you are in Marion and most of Lake counties, you fall under the St. Johns River Water Management District ( Home of the St. Johns River Water Management District). I believe they also require twice a week watering, but you can find out for sure at that website.

I'm amazed at how few people know about these restrictions, let alone what day/time they are supposed to be watering.

New lawns will often be watered more until established. The company that installed your sprinklers and that should have done your "orientation" can be very helpful in knowing what to expect. Personally, I wouldn't rely on water running down the street as an indicator mainly because the "soil" is mostly sand and water runs through it so fast.

No need to water in Summer
 

I think you'll find you are overwatering. You only need to water once a week for most of the year, 40 minutes for lawn, and 15 minutes for scrubs and flowers, and turn off your system for July, August and September, our rainy season. Been here 29 years and my lawn is beautiful.

Same. It works great. Plus,, it will skip watering days if significant rain is in the forecast...

This... I have 5 local weather stations in my immediate neighborhood. The closest is 5-6 houses away.

This restriction is not enforced so many don't care about or know about it.
