Common Bermuda folks, what height are you cutting right now?

I have a common Bermuda lawn. This is 100% not a fancy hybrid Bermuda that I see most folks on here have. I’ve got mine set to a three. I like it a little bit taller and I don’t want to have to water it intensively. I can only automatically water the grass twice a week here and it has been pretty hot lately, but I’m wondering if I should lower the cut just to see if it will fill in even more than it is now.
