Why KDJ couldn't see his attributes window without an enormous probability storm ?

Is it because as the world is a time loop, the little energy he needs to activate his attribute window is passed on through time and is amplified each time so seeing the attribute window is like watching into two mirrors that loops (I explain it very badly but yeah) and so the probability needed is way too big or even infinite.

And what would he see on his attribute window (apart from what we already know)

And what about him gaining insight on himself. And he never used omniscient reader viewpoint on himself did he ?
