B757 Idle Thrust & Stiction

[regor]

If a B757-200 is sat on a level runway with engines running, at idle, and the park brake is off, at what gross weight would you expect the A/C to begin rolling?

Does anyone know if there is any tabulated data on this, or if any flight manuals contain this information.

Any experiential information is also welcome.

Thanks

It will roll at around 100 tonnes, so probably will at MTOW too.

Not the kind of thing that is tabulated though.

Just as a matter of interest, would it make a difference if they were E4 or C engines? Do they have (significantly) different amounts of thrust at idle?
