One may be missing provided hole is covered.
Increase fuel consumption by 1%.

Reduce 1 engine inop ceiling by 250'.
Max take off weight must not be higher than 260 tons.
What is the MTOW of an SAA A340-300 (2 Winglets)?

The point being SC, that even if the MTOW is only increased by 2 Tons with 2 Winglets installed and assuming these Winglets do not tip the scale at 1 Ton each (ouch), then it IS worthwhile...
Considering these winglets are semi-composite i.e. Lightweight.
More Tons = More $$$'s Revenue
