You are trying to dictate to amanda, and that tends to be a hassle.  
With the inevitable, often human error generated reruns, 
(forgetting to change the tapes even after amanda sends you an 
email telling you too is a good example:-) that require the next 
tape in the tapecycle which in turn throws your carefully crafted 
schedule out the window, its easier to just let amanda do her 
thing.  She is very good at it.

Tapecycle is however many tapes you actually have in the rotation, 
and should be enough that you have at least 2 consequitive fulls of 
each entry in the disklist on hand at all times.  Here it runs 
every night, so the dumpcycle is one week or 7 days.  runspercycle 
is then 7, and tapecycle is 20.
