Is this Duplo train track under too much tension?

According to the author, in order to ensure that there is no angular misalignment in the layout, the number of left pieces minus the number of right pieces must be a multiple of 12. The author also mentions that the vectors from the start to the end of each piece should add up to zero for positional alignment. Interestingly, the coordinates of the layout consist of rational numbers and rational multiples of √3. To determine if the pieces form a loop, each piece type is assigned a list of four numbers and the loop is formed only if all four numbers sum to zero. The displacement of the layout is not zero, indicating that there is stress. The author suggests removing certain pieces and adding others to achieve an “exact” solution.
