If you are simply counting positions where the hash signature matches what is in the table, you should get 25% and higher. If you are counting positions where the hash table hit actually stops the search early due to a fail high/low or exact score match, this should be around 10% and get better as depth increases. fine #70 gets a huge percentage of hits... but there are only king moves for many plies..
