Elastic strain is still in the model and can still develop or might remain constant, separate from creep, depending on how the loading changes. The Creep Limit Ratio is the ratio of the equivalent creep strain increment to the equivalent elastic strain. It is intended as a quality control tool to limit how much path dependent creep strain develops within each time increment. A solver bisection is triggered when this limit is exceeded. The default value of 1.0 in Mechanical is completely arbitrary. If the elastic strain value in your application is very high (relative to creep) it might make sense to reduce this limit to a small fractional number well below 1.0.  If the elastic strain is very small, it might make sense to increase this limit to well above 1.0.  Setting it to zero just turns off this trigger altogether, which might also make sense, if the solver bisections are just slowing the run down for no good benefit in capturing better path dependence in the creep calculation.  Refer also to CUTCONTROL command in the MAPDL Command Reference Manual.
