I think the DASC (Defence Aviation Safety Centre) pay little regard to PPRune, as it is not an RAF site however, they DO take note of Murphy's and Condors and Human Factors Open Reports.
There are some very valid points here and a cut and paste job of the aforementioned points onto the official form(s) would have an impact and may get a result. And, the old adage "The more the merrier" is especially the case here-the more folks who raise the same points-the more likely that your complaints will be taken notice of and rectified.
