Abstract: We report our progress in combining a two-level sampling algorithm with distillation techniques for calculations of disconnected diagrams in quenched QCD. The simulations are performed on a single ensemble at $\beta=6.0$ and volume $V=16^3\times 64$, and at a pion mass of $m_\pi\approx 760~\mathrm{MeV}$.
