I have also set it to 25 yard parallax but at 8 it is less blurred than the 3-12, certainly not clear, at 10 and 12, probably quite a lot better, will check longer ranges on range tomorrow. Is it physically possible for a 44mm objective scope at 10x to have a sharp(ish) depth of field from say 8 to 45 yards? Must say though that a bit of blur at longer ranges does help with rangefinding if you know how much blur at your set ranges.
