Statistically, the ratio of any one card should be equivalent to the ratio of the whole set.
This is, of course, unless there are specific cards from each set that are much easier or much more difficult than normal.
So assuming that your ratio is correct for the set, then either your Nadja Plank is more common than normal or the script and blank backed Planks are much tougher than normal.
Of course, all of this is just to yank your chain :D
