What is going on is that around 5-6 times since they started the mrv program some months ago, they've changed the protocols such that all boxes had to be on the same CE. Sometimes that protocol stuck for a few weeks or months before they changed it again and once again required every box to come up to the minimum.
So sometimes you had to have them all on the same version, sometimes they could be on different ones as long as they were on the same internal rev of mrv code/protocols.
I think they changed it either last week or the week before, since people with older ce's couldnt mrv with the new ones. Not sure what they did this week since they dont tell us anything.
