Cyclone V vs Cyclone IV static power

Sound confusing from the service request. Currently what we are seeing here is significant static power increase from Cyclone IV to Cyclone V. I assume that since under worst case, we already have static power reduction, typical case there should be more power reduction. Just wonder why in typical case we see power increase here. Seems to contradict with the response provided by service request. Probably this is something worth highlighting to them.
