The passage time from a vertex $v$ to a vertex $w$ is defined as $\\inf_{\\pi:v\\rightarrow w}\\sum_{e\\in\\pi}t(e)$, where the infimum is over all paths $\\pi$ from $v$ to $w$, and the sum is over all edges $e$ of $\\pi$. Benjamini, Kalai and Schramm [2] proved that if the $t(e)$'s are i.i.d. two-valued positive random variables, the variance of the passage time from the vertex 0 to a vertex $v$ is sublinear in the distance from 0 to $v$.
