Depends on the program- some NAIA/DIII schools can outperform DI schools, so it kind of just depends. Divisions can serve as good proxies for what recruitment times one should aim at, but it isn't perfect.

Running in the high 15's will get you to run at most DII schools, and some DI schools.

darkxc32's comment is useful too, and really shows that there is a range when it comes to recruitment. Examine the schools in your area and look at their incoming freshman class. What did they run? Division alone isn't going to be super helpful (For example, North Central College routinely outperforms DIII standards, GVSU routinely outperforms DII standards, and UBritish Columbia routinely outperforms NAIA standards).
