I am wondering what the ripple is you are trying to describe, we are not talking about the heater elements I take it.
We must have different breaks over here as I am yet to see a starbreak that does not go back to the laminate. When glass breaks it predominatley breaks cone shaped, meaning there will be a smaller impact point than the overall damaged area. A bullseye is a classic example of this and it is only the outer limits of the bullseye that goes down to the laminate which is why it is a waste of time drilling into the centre a bullseye. However with a starbreak we have radiating legs going in all directions these will reach down to the laminate along most of their lenght. If when you flex a leg it opens slightly this is telling you the legs is opening on the far side from where you are pushing, for example the laminate surface. Some legs and only a few may close this will be legs that are also broken and open to the surface, there is a very slight possiblity that some of thses might not reach down to the laminate. It is very interesting to view damage from a side on perspective and you will see all that I am trying to explain. You will need a practise glass for this, just make some damage and look through it from the side of the glass. We find this totaly enlightening for most trainee's we get in.
