Not sure which program makes the decision, planner or something else,
but what you are seeing is a first check on each DLE and what it needs.
Then after all DLE's are determined individually, a check as to how close
to the average daily run size (tape usage) that comes in total. If low
by a significant amount, some promotion, as you observed, may be done
to try and achive a long-term balance.
