Improved Physical Attribute, Have I found a loophole? Options

[Guye Noir]

So, going through the rules for Adept powers, I notice that using the power Improved Physical Attribute allows the character to raise an attribute up to it's racial maximum for 1 power point per point of attribute. However, raising the attribute above the racial maximum costs 2 power points per point of attribute.

There is a slight problem: Suppose a character uses BPs to raise his agility to one point below it's racial max 5. He then spends one power point on the adept power Improved Attribute to raise his agility by one point 5(6). After a few 'runs this character decides to spend some karma to raise his natural agility by one point. His new agility score is 6(7), but he didn't have to spend extra power points to raise that attribute above it's racial max. He essentially spent 1 power point on something that was supposed to cost 2.

So... was this done on purpose? Is this supposed to be allowed? Also, why do Adepts have to "pay" extra to raise an attribute above its natural maximum while mundanes don't? In contrast to the Improve Attribute power, cyberware/bioware that raises attribute scores cost the same regardless if it's above or below the racial max.

These are the kinds of thoughts I have at 2:30 in the morning when I can't sleep.
