The reason I wrote we have to wait for him to show his real face, is because he doesn't have both values- indicating an aimboter-high.
If you remember, I wrote that correlated values of high accuracy and KPM indicate probably an aimboter.
In this case we have only one value with high numbers(accuracy).
And as you said, he hasn't played enough hours, so his kills are few to extract solid results.
Yes, most probably he is an aimboter, but evidence is not enough to put the tag of cheater on him, we also need high KPM, or something else(headshots, kill/hit ratio, a video), some strong evidence.
