Though it seems odd to me that a warship's astrogation computers would silently effectively default to fuel conservation over transit speed. Dropping to lower bands to use its grav wave does let you keep reactors shut down or at idle, and draw your power through the sails.
A merchant ship might choose to travel a while in the Beta or Gamma bands to avoid burning fuel - though even through I'm surprised that hydrogen savings (and longer service intervals on the fusion reactor) offset the lower utilization and extra days of paying the salaries and loan on the freighter on that leg of their travel.
But I'd think a warship would default to quickest safe transit routes and never would have offered to dip into lower bands to catch a wave. (Though it's certainly possible the training officer or captain or somebody changed the defaults in order to make it a learning exercise for Helen)
