upper += results[i].weight

All of the weights presumably have the same magnitude. The current logic sums them in descending order, adding highest weights first, which maximizes the approximation error of floating-point arithmetic. With #24 as it stands now, they will be summed in randomized order. To minimize the approximation error, the smallest terms should be added first.
