Acceptable HIT/MISS ratios

I was curious to know what most people thought was an acceptable HIT/MISS
ratio for the average cache. My server has around 27% HIT/70% MISS.
Is this what I can expect from general Internet users plus some smaller
ISP's hanging off our backbone?

Also, my figures for external fetches are quite disturbing: 87% DIRECT the
rest to my parent. If this sort of thing is normal could someone please
correct me? It would seem to me that the parent should have these sort of
fetches rather than a 'child' cache.
