Note that the mainlines come from the transpositiontable. With such a high loading factor i'm pretty sure that the real length is longer as it can retreive from hashtable. Score is 0.828 for Bxh7 after 17 hours though and my expectation is that to get the next PV i need to wait another 40 hours at least, and that the score hasn't changed too much, and i need my dual now to do other things!
