Do stiff mechanical systems (e.g. rock) react faster on stress rate changes than soft systems (e.g. soil)?

I have a rock specimen and a soil specimen. During my mechanical measurements I observed that the rock reacts much faster on stress rate changes (observable by a sharp kink in the deformation...

Are there recommended settings (rotational speed, drift) for overcoring a mudstone in a lab?

I want to overcore a drilled specimen from the field for triaxial testing. Now I need appropriate settings for the overcoring machine to get (nearly) undisturbed mudrock specimen.
