Double Back
"Older built planes never had wings that were absolutely identical, there was just too much spread in machining techniques. So they ended up with different lifting values"
You also could have mentioned that the Airbus fly-by-wire planes, by eliminating flying control cables and pulleys, also eliminate the need for rigging. Within reasonable limits, the fbw doesn't care about small left-right build differences.
