Yeah... these rules seem a little too simple to me. I'd think that
updgrading a program should take slightly longer. Otherwise, there's no
reason to write things from scratch, because some Restrict-10 Area DINAB
targeting program is actually just the result of a slow improvement of
that Restrict-3 you had five years ago.
