I can't speak much to Southern grasses, but I find it hard to believe that 12 minutes twice a week is too much water... We do that much every day just to wash dog urine...
If one is adept in noticing what water-stressed grass looks like before irrigation, that is good, but my idea is to look at the soil in the root zone first hand... if there is enough moisture or not can more easily be determined that way, IMO...
But either way you do it, you'll want to do it as noted on turfmd101's listed #5... allowing the roots to dry a bit at the surface enhances aeration and microbial activity of greater variety, each of which enhances soil structure and soil health...

A question about applying K, this time of year and even in the Spring for Northern areas,,, What's up with that??? We sometimes do K apps in the Fall for winter protection, but it is generally not that needed of a nutrient... Has this notion changed??? and should I be thinking about more potassium on a regular basis???
Now that I know that clay's texture(platelets) has nothing to do with water infiltration, percolation, or drainage
,,, I wonder what does...
