@tobi82 I think it says more about you than you might think, how dismissive you are of "community surveys". In a disease where is no objective data, we will always depend on subjective patient reporting. That survey by Gez (a medial researcher by trade) was answered by well over 2000 people (if my memory serves me right). I also remember a later study that confirmed the 25/25/50 finding. Still looking for it though. If i can be arsed. @Infoseepage
