OK, I agree.

Ah, you are right. I think I confused offset and relative size.

By "values" you mean both offset and size? Ok I guess we can still convert
<custom offset>,<custom size> to "super 58%" at saving time if we know
the default offset for "super". This would be a nicer XML than saving both
values numerically, for the reader applications that only support sub/super
and not custom sizes (I guess this is the whole reason for the sub and super
values...).
