Which makes it questionable why Krell Moset wasn't one of them...since the data was in Voyager's memory banks, it's not like he was unknown to the Federation...
They already gave us the same example in TNG when Geordi created the hologram of the engineer that designed the new warp core for the Enterprise. When then learned upon meeting the real her, the personality profile was incorrect.
The data base may contain the accomplishments of people but not their complete personal profile or the means in which they achieved such goals.
