It may just be that Vas found he'd taken Rybka as far as he could and that to continue developing it further it would be necessary for him to go back and find out the precise point where he'd unintentionally taken a path  which pinched off further natural improvement.Rather than break his back going back,he opted,instead, to squeeze all he could from what he had by providing it with the ever growing computing hardware which LC'S Cluster would provide. For the vast bulk of us Rybka devotees this decision ,if so,is barren of benefit.The cluster will certainly make Rybka 4 all it can possibly be but for us all it can possibly be is Rybka 4(or,4.1)and that's already proved to be inadequate.I hope I'm wrong about all of this but I don't think I am.
