Yes, when we do dual entry, that substitutes for proofing for us. But
in the case of transcribing hand-written, prose notes into coded,
digitizable format, i think that dual entry may be prohibitive and
proofing much faster and less labor intensive. We will continue to
think about it and see how dual entry goes for a small part of it,,
as I mentioned earlier. I like your idea of comparing that with
proofing to see which is more time consuming. Lacey, let us know your
thoughts.
