I could swear that you are experiencing the great Oracle feature called "bind 
peeking" at work ...

> I could have swarn I read that if you use bind variables oracle ignores 
histograms. We are
noticing different query plans based on the number of buckets our histograms 
have while
our queries are using bind variables.

and it is
changing based on number of buckets even when bind variables are
used.
