ok, as a sesoned tech, the reason for your signal disparity, is the lengnth of cable from each run to each receiver, the receivers closest to the dish will have the strongest signal strenth, that you did not inform me of, the receiver farthes away from the dish, would have a lower signal, now i some cases it is receiver specific, i can hook up a 522,322, and gell a 100 signal, and then hook up a 311 or 111, and get a 125, so signal strenght has to do with the receiver you are dealing with and aslo cable run so if that receiver, with the lower strenght is farthest from the dish, then that would be apropriate, otherwise dont worry because anything over 70 percent shouldnt have that much rain fade.
