Does pasting the same text twice change the AI detector score?
I test a lot of text through detectors for the agency, mostly to see how our own drafts look before a client's compliance team runs them. Yesterday I had a 140 word product blurb that one tool refused to score because it was under the minimum length. Out of curiosity I pasted it twice into the box, 280 words, and it scored. The number was different from what a tool without a minimum gave on the original.

Does duplicating text change the score because the detector sees more words, or because repetition itself looks odd to it? Is the doubled score more reliable, less reliable, or meaningless? And is there a sensible way to check short text at all?
I am not trying to game anything. I want to know how much weight any number on short copy deserves.
