I understand.
However, i prefer having it in one place.  After all, it's not needed
anywhere else, nothing depends on it (unlike design_size).

On the other hand, if you wanted to make a systematic change (i.e.
increase value by 2 everywhere), using algorithm is cleaner.

Probably redesign.  Everything that can reasonably be described by an
algorithm should be done so (in my opinion).  If an algorithm exists,
it explains why things are the way they are; it can also be applied in
cases not originally predicted by the author.
In this case i think the algorithm approach is reasonable, but I don't
feel extremely strongly about that.
