yes, your CFL is correct. and it is influenced by the mesh size.
reference strain rate is the strain rate in your experiment which is used to find the EPS vs Stress. and check your material definition, only use the plastic terms and your elastic terms comes from isotopic elastic terms. Use only 5-8 points in the material definition.
check the following links for futher help
