Duchess Evestireni's effort takes some more time than expected at 6 hours, but that has more to do with the lab space having been reorganized for her cybernetic experiments than with her lack of skill. Eventually she makes up for it by jury-rigging a highly efficient refining circuit optimizing refining time that will still put her ahead of ETA, only requiring 36 hours to process all 80 tons of fuel.
Dr. Lizbeth Hayden, who assisted her, is simply marvelled. "Your Grace, I could only wish to be half as good as you at this thing... at half as youthful and beautiful a face." She grabs the intercom and lets her husband know on the internal circuit: "Hubby, we are done down here, and even ahead of schedule at 36 hours. You should get some rest now, and maybe another time before the process is done. You've heard your doctor's orders, haven't you? Not letting you plot our course on bloodshot eyes just urging to get closed. Maybe let's have one of the younglings have a shot at it while you rest, like what's-his-name, Hans or something?"
