Sorry Uri,

i didn't know that your exact calculation just holds for one direction. Shame on
me because i estimated the stupid other direction:

Fritz3 on p90 is IM (2350 ELO) at normal rate of play. And doubling the speed
four times seduced me to the wrong assumption that Fritz3 on a 1.44 GHz machine
should reach 2750 ELO ... enough to compete with Kasparov.

But now i fear that you must've been right as took the other direction and

Perhaps i'll never understand this difficult ELO algebra for computer chess :-(

Depending on master's style and opening choice you might be right or wrong :-)
