"Non-harmful" mutations are considered those that are not detrimental to immediate
survivability. These mutants are still subject to the baggage principle, however. In
other words, when baggage is accumulated, there will be a slight hindrance to the
competitiveness of the organisms, even though the first one or two units of PAES
(potential for an additional energy source) may not have enough impact to justify
calculating a diminished competitiveness.
