By the way, this is where you can make the difference between strain 
rate and gradient of velocity.
Your sentence is formaly wrong : updating relative velocities needs the 
gradient of velocity (obviously!), not the strain rate tensor.
Strain rate, being the symmetric part of velGrad, is not enough to 
describe the transformations of the period.
You will not see any difference in the usual triaxial path, but you will 
in simple shear.
