I believe the actual split up stats are 1180 Blue and 320 Yellow.
As for numbering, of the 1180 Blue MP3s, 250 are in Canada and have no production numbers unfortunately. As far as I understand, the remaining Yellow and Blue MP3s that exist in the states are mixed up in terms of production numbers...what I mean to say is that there isn't a set grouping of Blue and Yellow ones...not any pattern I've seen from other members numbers anyhow.
