How to sharpen a serrated edge

I have been doing this way as per Sal's instructional video for about 10 years and it's fast and produces excellent results for me. Also, the fine alumina ceramics don't round out the tips like people seem to think, but... even if it did then they would only cut more efficiently the more the scallops become "continuous" but still have the aggressiveness to power through fibrous materials (sort of like the old Kershaw scalloped serrations).
