Quote - Deltas are the difference between morphed and original X Y Z vertices.
Deltas are stores as a table
index dx dy dz
index dx dy dz
........................
Where indez is the vertice number of the body or prop part and dx = xmorphed - x original.
Index is a long integer and dx, dy,dz are floating point numbers.
If dx and dy and dz becomes too small, near zero or zero dx, dy,dz are not stored in the table
You can clean and optimize a morph target removing useless deltas that are too small.

Theoretically then it sounds like I could copy deltas from one cr2, and paste them into another (with same geometry), and not get any shifts. 
The deltas that are giving me grief haven't even been rounded off yet. Well, darn!
