Reverse SLE derivative bound above the space-filling threshold

If $\kappa >8$, then for every $0<\alpha <(1-8/\kappa )/2$ and fixed $T$, there is an almost surely finite random $C$ such thatfor $|x|\le 1$ and $0<y\le 1$. The proof combines the derivative martingale, Markov inequality, a dyadic lattice, the Borel-Cantelli lemmas, and the Koebe distortion theorem.
