hi mike , i also was curios as to wether they backdate payments after a review if award was higher ,, ,all i know is that a friend of my daughters had a review and her new award was higher than exsisting award before review ,, she had a payment made to her account which would suggest the difference in new award worked out to be a backdated payment . she wasnt expecting any payments backdated and didnt have a letter that stated this either , so not sure what to make of it ,
