RX100 - How effective is the SteadyShot?

i posted an example shot last night which no one responded to where one image was shot at a focal length of 100mm at 1/25th of a second. at iso6400, not that that matters to the stabilization, but the quality at that iso was why i posted the shot in the first place.

so what's that, 2 full stops below the classic recommendation of 1/focal_length and much better if you believe that a more conservative formula is needed for m43rds, right?
