It's low. Remember that if you're caching queries which return results that are often changing, that INSERTs and UPDATEs to the cached result set tables will force the query cache to invalidate the result block, therefore forcing a new insert into the cache.
Do the queries you are caching contain lots of variable data which changes frequently? For instance, are you caching a "most popular top 10" list or something like that which changes frequently?
