Sounds like some development-policy rule-of-thumb, kindof like the
9-to-1 resistance ratio for biasing a class-A common-emitter bipolar
transistor amplifier stage.  It seems that, since the size of the 'a',
(root) partition is roughly proportional to the size of the system,
then the size of the 'b' (default swapping) partition would also be
roughly proportional to the size of the 'a' partition.

Certainly nothing prevents your changing them to get improved
performance in a manner that improves the fulfillment of your
particular needs.
