The comparison between the doublet de fence and the welsh jack is most telling that they are made from the same number of layers of fabrics (of similar types, I think), but cost different amounts to make up, in much the same way that doublets are cheaper to make than coats (though the coat usually has more spent on the fabric).
This is why I feel that they are very separate items, possibly more to the Medieval mind, than to ours.
But you've just given a case for a doublet of fence being different from a jack in the medieval mind; not for an arming doublet and a jack.
My understand is that a doublet of fence is, for want of a better definition, is a civillian rather than military protective garment; a clear medieval distinction makes sense to me also.
I'd like to see some evidence that suggests an arming doublet is distinct and different in the medieval mind to a jack, i.e. they are different types of garment with fundemental differences.

Again, I think you need to show there is a distinction between heavily and lightly padded garments, and not a sliding scale.
