[Babase] RE: FW: LAH has a naughty focal point sample

Okay, this is what it says now:

Females may have juvenile (Stype=J) SAMPLES rows until their first
conception. Males (or those of unknown sex) may have juvenile (Stype=J)
SAMPLES rows for up to but not including 1 year after maturity
(MATUREDATES.Matured).

Only females may have female samples (Stype=F). Females may not have female
samples more than 1 year before maturity (MATUREDATES.Matured).

What if we add:

Although the goal is to sample females as juveniles only prior to menarche
and exclusively as adults following menarche, there is a margin for error.
For example, a female may have a false start toward menarche where she
begins to swell and is sampled as an adult but then the swelling turns out
to be extremely small and, in hind sight, is not considered to be the onset
of menarche.  On the other hand, females may continue to be sampled as
juveniles for a short period of time after onset of menarche.  Since the two
sample types contain different data, the data collected cannot be easily
changed from juvenile to adult or vice versa.  Therefore, in order to
prevent loss of data for females near menarche, juvenile data is allowed for
a short time following the maturedate and adult data is allowed for a short
time prior to the maturedate.

If you have all this in your brain and feel like writing a footnote
for the docs go ahead and I'll drop it in.
