Double Double Choco

This is two stacked Double Chocos - each number N in the center grid is the sum of two Double Choco clues between 1 and N-1, inclusive, in the same location in the left and right grids.
Once the clues are placed, the left and right grids are regular Double Choco grids. To differentiate the two grids, the top left number of the left grid is smaller than the top left number of the right grid.
