  I perform tracking simulations to fit various measurements of the
polarization for a stored uncooled polarized deuteron beam, published in the
recent paper by Benati et. al (P. Benati {\em et al.}, {\it Phys. Rev. ST
Accel. Beams} {\bf 15}, 124202 (2012)). The collaboration kindly sent me
datafiles of the polarization measurements, and also pertinent details of the
experimental data acquisition procedure. The latter are essential to obtain
quantitative fits to the data. I describe my findings and inferences from the
data. In some cases I offer alternative interpretations of the data from that
given by Benati et. al. I also correct some mistakes in my recent paper (S. R.
Mane, {\em Nucl. Inst. Meth.} {\bf 726} 104--112 (2013)).
