HIT rate first level Web cache compared to Top-level Web cache..

Dear cachers,

        Can someone explain to me why first level Web caches does have a
higher hit-rate then top-level web caching servers ??
A first level cache get's all the nice cacheble objects which might be
accessed again a lot in case of a homogeneous'user group.. All the
unresolvable requests are routed through the Top-level cache.. However,
if the top-level Web cache does not have any shortage of resources, the
HIT rate of the top-level cache might be close to that of the first level
cache..

When I look at the statistics of a Desire/Web-caching partner, it seems
to be the way around... The HIT-rate of the "Second level cache" (the
Top-level Cache) is much higher (abount 50% in March) then the HIT-rate
of a First level Web caching-server (on an average32% during the same
period)??

can this be true or am I mistaken ??

Cheers, Henny
