Ok, now I'm following you....I don't live and breathe this like you and
Chris do. =)
If the dns3.uiowa.edu's cache was flushed for sioux-center.k12.ia.us, what
do you think the query results for
dig @DNS3.UIOWA.EDU sioux-center.k12.ia.us ns +noall +answer
would be?

No. If that was the case no delegations would work unless the name
server was also authoritative for the subdomain.
