Again guys I am not knocking it at all it just seems odd to cut that tall because nobody cuts that tall around here and we have the same types of grass. A good portion of this area the people have there lawns treated and unless it gets super hot and bone dry you don't see lawns brown out here. Almost nobody here has irrigation either.
This is my own personal untreated lawn that I cut at 3".
Customers at 3"
This one was super early in the year cut at 2 3/4
