Frank: It could be accurate. I mean, if you wish to use the phrace, go ahead. For example, I could say; "My answer is barely accurate." "The facts in the newspaper are barely accurate." No problems there. But how would "I" communicate this? Like so. "The results are a mere approximation at best." "The results only offer an average." "The results are inconclusive." "The results are not entirely conclusive." "The results are more suggestive than an explicit demonstration." "The results do not show any kind of finality." "The results show that further research is necessary to obtain to a conclusive answer." .
