But I think you are using the P-90 h/day values without changing them, don't you? I think the actual performance values are to be computed again to be useful, because there are many people upgrading and therefore ranked high but showing lower performance values at P-90 h/day as other participants ranked nearby. i.e. today I'm ranked at 445 with 22.882 years/148 exponents(IPS)/182,22 P-90 h/day Currently I'm running Prime95 on three machines (2 GHz total) equal to 22,0 P-90 CPUs. This means 528 P-90 h/day but completing one LL-test at 12M range only adds less than five P-90 h/day. There's a difference between 182 P-90 h/day at top producers list and 528 P-90 h/day (actual performance). How to calculate the actual performance of an upgraded account of user X? To do this I'm calculating the average P-90 h/day of such participants near the rank of user X having higher values than X. The other users near X with lower values did some upgrading recently too and therefore are to be neglected. Computing the average out of 10 such values in front and 10 such values behind the rank of user X works well. I called it the local average. Using 20 such values nearby my own ranked ID (dismit) gives the local average of 310 P-90 h/day. Of course, this isn't a very good approximation. But the 182 P-90 h/day on the list means 58.7% of the local average of 310 P-90 h/day. Thus divide the local average of 310 by 0,587 and use the result which is very near to the already known performance of 528 P-90 h/day. Does anybody know a pretty formula of this algorithm? Why does it work at all? Have fun Dieter Schmitt - -----Urspr�ngliche Nachricht----- Von: "Steve" <[EMAIL PROTECTED]> An: <[EMAIL PROTECTED]> Gesendet: Donnerstag, 15.
