While i understand some people get claims challenged, i really think we need to look the wider picture and ask how many claims get challenged overall.
Just looking here and on arrse, it seems that only a tiny minority of people get challenges, and talking widely with friends at all ranks, aain very very few have an issue with the system or the adminers supporting them. Now i could just be incredibly lucky with my sample group, but i do think that its a good system and that the overwhelming majority of claims go through without drama or problems. Perhaps thats why we seem to hear the same tiny number of stories about such specific claims - precisely because they are so unusual that it sticks in peoples memories?
