It might well have substantial uncertainty, in either direction. Suppose it's 30% plus or minus 20%, a huge amount of uncertainty. That's still
absolutely a reasonable threshold someone could use as the basis for a decision.
The exact numbers here are examples, not the determining factor here, nor do most organizations express them quantitatively.
The important point is that organizations can and do have a different threshold for action. You could absolutely argue about whether an organization has the right threshold, but I don't think there's a case for a deontological requirement that every organization's threshold for taking any action at all must be the same as the threshold for conviction in a court. (Leaving aside that that would utterly invalidate freedom of association.)
