You are right, i was in automatic mode when writing you this response as i know what you say is correct about the time control and the Hi-Mark test! It will make no difference where you have the time control set for the, but for Hiarcs7.32 it makes a difference how large you set the Hash size, as the smaller you set the hash size the higher the Hi-Mark goes! What you say about Hiarcs taking longer to clear its Hash tables before the Hi-Mark test is probably the answer to this weird response. If i set my hash table size to 1 or 2Mb, then it appears that i get a more accurate Hi-Mark. When i do this my Hi-Mark is 194 at 28KN/S. If you do this with Fritz, will it also affect its Hi-Mark like this? Best regards, Terry
