In principle, if there are two sets of tees, one selection may be easy, the other may be hard, "medium" for a mix of them.
In reality, the mix is arbitrary, sometimes providing the same tees for easy AND hard. You'' never know.
I learned this the hard way when checking out the pins and distances at KIA #9 from Legend tees. 1st game "easy", I get the front pin. 2nd game "hard", I play through 1 - 8 again only to find the front pin again :(
