This is just to note that in addition to having the sex skin sizes starting
with 1999, we are almost finished adding the pcs coloration. This was
stimulated by Jacinta's pregnancy failure ms and the fact that everyone
else uses pcs color to determine pregnancy whereas we have always used
earlier criteria and now have the hormonal data as well in some cases. We
have noted that pcs color change comes later; it is also very variable in
timing, but as far as I know, neither we nor others have quantitative
information on this. We will now have it electronically for the years for
which we have hormonal data (and may soon be able to related color change
to hormonal change) and for most of the years for which we have data on sex
skin size electronically.
