And you want to say what with this post?I agree, all sorts of actual army reports, testing and battlefield evaluations have proven that all airforces vastly overestimated or exaggerated their kill-counts.
None of that has anything to do with "blogs" stating such things, and it certainly isn't a case of spreading myths themselves. It can be found in actual reports from the time, and gets covered in all sorts of reference books and papers from highly acclaimed historians.
