The reason for no one listed from those dates(1997-2001) is because after the GAT for OTs release, there were no new OTVlll completions until about 2001. No one that completed OTVll previous to 1995 GAT release were allowed to do OTVlll. All people on OTVll, finished with OTVll or OTVlll(before GAT) had to go back to Flag to do the Solo NOts Certainty Course, then redo OTVll, and only then were allowed to do OTVlll. It took years for anyone to finish after that.
I don't know about the 3000 OTVlll number but I am sure of what I wrote. That number I gave was those OTVllls who completed OTVlll AFTER Golden Age of Tech and redoing OTVll, hence the difference probably. One can see, if the 3000 number you write of is correct which I VERY much doubt, that there are quite a number of "OTVllls" that have not gone to do the Solo Nots Certainty course and have, again if that number is correct, fallen by the wayside.
