Moisture Level for Different Grasses

Just switched to a Flex/Daily schedule. Seems to be watering more than necessary for our Argentine Bahiagrass lawn. Would a non-default Moisture Level be appropriate? If so, what? Thanks.

That’s a warm season grass right?

I remember bahiagrass from Alabama. It’s grown a lot as a pasture grass for hay, but is an extremely tough lawn. I think I would give it a .55 crop coefficient, in between Bermuda and buffalograss.
