There is a problem with the definitions of terminology. While wavy is great as a generic description, there is a distinction to be made. Several examples of "waves" in the (unreferenced) illustrations above in Post #105 are actually 'wavey' or 'undy' in heraldic terminology. Round at the top and round on the bottom, like a sine wave. Or round on both sides, if you prefer.
The "waves" in the VMs (items #2 & #3 from map above Post #112, plus the clarified example) are only rounded on one side and decidedly pointed on the other. This type of line structure is designated by the heraldic terms 'engrailed" and 'invected' (points out or points in.) So, while the structure certainly looks like waves, that is the wrong terminology.
The problem with engrailed/invected lines is - in relation to what? The examples in items #2 & #3 pose the same question of relationship. Are these examples of waves from the ocean washing up on strange shores? If so, the pointed side is oriented in the wrong direction.
On the other hand, if waves are emanating from the rosettes, the waves would be moving away, depicted like a cloud band and the hatching lines as rays of light would further confirm this interpretation.
While some rosettes do have illustrations that can be interpreted as geographical representations, other rosettes seem to be lacking. Their patterns are quite abstract. What's important here is the text, the twice-marked band in the central rosette.
