As I may have mentioned, I have had miserable luck sharpening drill bits, be it by hand, old General jig, or Drill Dr. They just don't cut like a factory bit. Add to that, there is really no reason not to be using split-points, which are a little tricky to grind. ( and a Drill Dr. that does split points is expensive)
I recently saw a video on bit sharpening machines. Not a single one could match a factory fresh bit ( chisel point) So, what are the factories doing differently? Sure, small bits I buy by the pack and don't worry about it, but from about 1/4 up, they get darn right pricey. From what I see, the Drill Dr. is a bit rough and I never seem to get the relief sufficient. And yes, been through the instructions a dozen times, so I sold my machine. I have been getting rid of everything I don't use to declutter and be able to fine what I do use.
