Hi The next thing would be to see the position (at ply 3) that the comps are crunching on at the moment :-) (but pls no movement for each calculated pos :-) ) Because you have the KNPS now you can either ask if someone is entering information about the processor/speed/hash (or identify these three values by the client) and you would have a nice database about relativ processor-speeds itself. With a database big enough you could see when the pocessors reach the point where it is sensless to add more hash! ...
