You can use any x value for m(x), including the x_i values and anything
in between.  In fact there is no need to you splines for interpolation.

For the "line" case, use (say) 10 * the _step_ you chose between x values.
For the "xy" case, use something like 10 * (last_x - first_x) / N.

(This way the half life does not change if you add more equidistant data
points.)
