Additivity conjecture for colliding jamiton lengths

Let two jamitons collide, and denote their lengths before collision by $L$ and $L_{\mathrm{test}}$, and the length of the resulting jamiton by $L_{\mathrm{col}}$. Jamiton-length additivity conjecture. The length of the jamiton after colliding corresponds to the sum of the lengths of the colliding jamitons, that is, $L_{\mathrm{col}}=L+L_{\mathrm{test}}$. Numerical simulations show a small normalized discrepancy, particularly for $\tau=5$, and the source suggests that the remaining differences may be numerical errors; an exact additivity result is not established.
