You mustve missed the part where i spoke of consistency?
Ive played at the pro level. Nobody prefires with perfect robotic consistency.
I dont care if it takes 50 matches of data for the statistical model to call it inhuman.
Valve has enough data that they could easily make the threshold for a ban something like '10x more consistent at pre-firing than any pro has ever been' with a high confidence borne over many engagements in many matches.
