Hong, No and Oh found a general upper bound $s_L(K) \\leq 3 c(K) +2$. A rational link can be represented by a lattice presentation with exactly 4 $z$-sticks.\n  An $n$-circuit is the disjoint union of $n$ arcs in the lattice plane $\\mathbb{Z}^2$. An $n$-circuit presentation is an embedding obtained from the $n$-circuit by connecting each $n$ pair of vertices with one line segment above the circuit.
