If you intend to sprinkle all in 1 day, then go for it. If you want to give it a light sprinkling every day, then that is a bad idea. You want to give it a good soaking down deep into the soil. You can't do that with daily sprinkling.

No, I mean that I want to stand there once a week or so (depending on weather) and soak the lawn about 1-inch worth of water (it's very flat).
I'm aware of the problems with watering too lightly.

I think your approach should work just fine. If you don't mind standing there holding the hose, I say go for it. You lose less to evaporation that way and also have better control over the water.

I do it do depending on the weather. I set my end hose head to shower. This way, the chlorine gets removed too.
