DM - Spitfire wings made of concrete?

Why should the spit be more durable than the messer? The messer is the smaller aircraft with smaller wings and its empty weight is almost identical to that of the spit. One should think that it was hence built tougher.

We can't read from that values which aircraft is tougher, because the parts may have a different size in each aircraft.

One explanation for the 100 values could be that the Spitfire is the reference implementation. If the wing of the Hurricane would be 25% tougher than that of a Spitfire it would have the value 125 and so on.
