PEK-EWR GPU clearing probability

Hi all,

First time posting here. Very helpful forum, have been reading it a lot.

For people familiar with the PEK-EWR route, what is the probability that R space will show up (for GPU to clear) for August 16?

Right now, R and RN are currently 0:
Available Cabins: J9, JN9, C9, D0, Z0, ZN0, P0, PN0, R0, RN0, IN0, I0, Y9, YN9, B9, M9, E9, U9, H9, HN9, Q0, V0, W0, S0, T0, L0, K0, G0, N0, XN0, X0

Thanks!
