ACS element text (the applicant demonstrates understanding of)

A stabilized approach, including energy management concepts.

Bottom line

If there is a deviation from the desired altitude/distance target, the energy state needs to be adjusted. Numerous power fluctuations or repeated deployment and stowing of speed brakes is an indication of either pilot failure to adequately plan and/or manage the descent, or a poorly designed arrival procedure.
