Confusion about the running time

[FlyingGaifield]

In the original paper, we can roughly get that when using model "8x multi", EPE is 1.1 (from table 1 ) and running time is 0.015 (from table 2, which is roughly 60fps).

In your implementation, you get 30FPS using model "8x single" while getting epe 1.38 Can you explain it more ? Or maybe the running time 0.015 is't corresponding to "8x multi"?
