Adding/integrating a smaller scall/double strand?

Hey,

I need smaller numbers for my scale, so would doing this [above] - correct me if I'm wrong - be the place to extend the scale downwards? I guess the same principle would apply if you were doing double strand stuff (i.e. multiple scales)?

If so, I would have to update this piece of code in _typeplate.scss:
// Multi-dimensional array, where:
// the first value is the name of the class
// and the second value is the variable for the size
$sizes: tera $tera, giga $giga, mega $mega, alpha $alpha, beta $beta, gamma $gamma, delta $delta, epsilon $epsilon, zeta $zeta;

... which would dictate this should be located in _vars-typeplate.scss too? Remember, I don't want to have to edit _typeplate.scss itself! :P

Best regards,
