Yes, but this doesn't prove much with such a small number of test
patches. By setting -r0 the interpolation between the test patches
has low stiffness, and therefore may model the underlying
device behaviour in a _worse_ fashion than what you had before
without -r0. Remember that the real measure of accuracy is to the
actual underlying device behaviour, not the self fit to the test
patches.
