Predicting the number of array instances and empty rotation

Hey, whatsup!

Is there a rule of thumb you use to determine the number of array instances and how many degrees you rotate your empty? I've remade the the flute model in a seperate blender project just to recreate the model and the way I manage to do it is by trial and error. Is there a "smarter" way to do it?

Thanks in advance!

    You can calculate the number of arrays needed by knowing the circumference of your object and the percentage of that circumference taken up by the partial piece. 

    For example, if your partial piece is exactly 1/4 of a circle, then you'll rotate your empty 90 degrees, such that each arrayed instance adds another 1/4 of the pie.
