I think this setting should be set based on your environment. I have APs in every "teaching space" like classrooms, gyms, offices, halls, etc.. When I had this setting to low I found clients did not always roam when a student switched classes or sometimes they would associate to horrible APs. I found that 24Mbps is the sweet spot for my environment. Cheers,

Usually I see that set to 1mbps.
