[Babase] Matured Dates after Statdate

Hi Susan,
I think the only outstanding individual to date is WAR, a male. (I've
just figured out solutions for three females with a similar problem
(MAV, ROV, DEE).
WAR was first censused in Altos group on Jan 19, 1977. He was last
censused in Altos groups on 1978-10-16 (so statdate = 1978-10-16).
Altos census continued after this but WAR was not part of it. This was
not surprising since he had been missing from the group during some Oct
census days. I specifically checked the Sept 1980 data (his supposed
maturedate was 1980-09-01) to see if there was a record of his
reappearance. There was not. His birthday was estimated to be 1966 so
a 1980 maturedate seems way out of bounds. He was probably matured by
the time he was being census in 1977, but I can't find a specific place
where it confirms maturity so I'm not comfortable changing the date to
something earlier.
All this comes from the old data sheets I sent to Duke recently. I
think Leah was going to have you review this so I'm not sure if that was
the intent of her original email about the statdate/maturedate issue.
