This test is actually fairly well validated. The purpose isn't to specifically diagnose your problems, it is to find the floor for how much trauma you may have experienced. Sure, some may have had parents under the influence occasionally while others witnessed heavy usage in front of them. The point is that even for the "light" case, that is a significant issue.
Think of it as childhood trauma triage. It is a good first pass to help people understand their past and maybe help some people understand that their past is more traumatic than they realize.
I don't doubt it's well validated, and the point of it also is clear. Based on the questions I could appreciate exactly your point -- people with some mixture of traumatic experiences will score higher, people without (or with fewer) will score lower. I imagine, as a total laymen in this field, the intended application is surveying large groups to focus resources, or perhaps as intake material.
But sharing and comparing scores on an internet forum seems (to me, as a laymen) outside of the test's design purpose. Initially I thought I would share my experiences here, but like mentioned in other comments -- I just don't want to breathe life into any of that. I hope other people who participated in the discussion found catharsis at least.
