5 piece wings

[Ronen Tat]

Obviously I was not clear enough, I hope this makes more sense:
Providing the total body thickness is the same no matter how laminates it contains, my question is which (top/back or core) needs to be cut thinner when you add more laminates.
Looking at your pictures it seems to me that with 3 piece wings the body core piece is thicker than it is in a 5 piece wings... while the top & back stay the same. Is that right?
Yes, my bass has the 5 piece body wings option...
