Improved Ability Question Options

[CitM]

Hi guys,

first of all two relevant passages from the book:

Skills:

p. 129 The skill Rating is a numerical value ranging from 1,
representing the most rudimentary skill, to 12 (or 13 with
the Aptitude quality) representing the height of sentient
achievement.

Improved Ability Adeptpower:

p. 309: This power increases the Rating of a specific Combat,
Physical, Social, Technical, or Vehicle skill per level of
the power. You need to know the skill in order to buy this
power for it, and you can’t buy it for skill groups. The maximum
improvement possible is your current skill level x 1.5
(rounded up).

I was thinking, why is everyone assuming that adepts can go beyond 12 and dont just reach the maximum rating at this power "faster/ earlier"?

It says, "skill rating is ranging from 1 ... to 12" and "this power increases the rating of a skill".

I know adepts could go til "maximum x 1,5" in sr4 but i dont get why it should be the same here.

Any ideas?
