PC"I can only conclude that there were 2 double prints to bring the total 350-only arrangement to 216 cards."
You also conclude that there must be three double-prints in the 150/350 Series (to get to a multiple of 12 in that series), since there might be 3 that need to be moved to the 150 Only series (which results in a multiple of 12 in that series).
You are making assumptions and calculations to force a multiple of 12 in series where the multiple does not exist, and I disagree with that.
And I completely understand the super-prints, and why you would want to include them in the 350 series. The only problem with doing that is they are not 350-Only series cards.
