Strange cookie behavior using HttpUserIdModule

I'm seeing a strange behavior using the HttpUserIdModule. I am seeing significantly more set operations that I would expect. The ratio of about 50% sets to 50% gets remains constant regardless of the days covered. So, if I include 1 day then percentage is the same as if I include several days.
The usage pattern of the clients and the sheer volume of users would indicate that we would not see 50% day after day.
So, on to specifics:
userid_p3p 'policyref="/w3c/p3p.xml", CP="CUR ADM OUR NOR STA NID"';
Requests flow in from
Client -> DNS load balance -> HA load balance -> 1 of 6 nginx servers
HA load balance is HAProxy.
I am trying to figure out if this is a user agent not respecting the cookie or something else.
Has anyone seen strange results utilizing this setup?
