Dumpcycle and runspercycle must both be considered.

Amanda attempts to have at least one level 0 (full dump) of each
DLE (DiskList Entry) each dumpcycle number of days or each number
of runs per cycle.  So if you have a dumpcycle == 10 days and
only run amdump every other day (runspercycle == 5) then amanda
checks each DLE to see if the last level 0 for that DLE was equal
to or greater than 10 days earlier or 5 runs ago.

Note, because of amanda's "dynamic scheduling", factors other than
dumpcycle or runspercycle may cause a DLE to receive a level 0
earlier than its normal dumpcycle.  For that DLE the hypothetical
10 day/5 run cycle starts over.
