When the cache has reached about 1 weeks worth of content only very marginal additional gains in hit ratio is seen. But the it ratio do continue to climb slightly at least for a month. But not very much. After that it's impossible to say from the data I have seen. Too much other variables impacting the result such as user behavior, different seasons etc.. making any changes in hit ratio due to cache size hide somewhere far below the noise level..
