You can approximated the MIL 55310 between two points in time as
f(t2) - f(t1) = Aln(t2/t1)
A = ( f(t2) - f(t1) )/ln(t2/t1)
Looking at some of your plots it looks like between the end of year 1 and
year 10 you age from 20 ppb to 65 ppb,
A ~ 20
The next plot "Lars_ForceAcoef", is a fit with the A coefficient forced to
be 2 and 20.
