A related rule can be found in the dilemma glossary entry:
A requirement for multiples of a skill, such as "2 Navigation", may be met by two personnel with Navigation or by one personnel with Navigation x2.
So again, why can't my 33 Tepos contribute CUNNINGx1 to 33>32, or my 15 Tepos contribute CUNNINGx5 to 75>32?
Then there's helps:
A personnel helps solve a mission or helps complete an objective if they actively contribute a skill, attribute, or characteristic required by the mission or objective. Just being in the Away Team or crew is not "helping."
By bumping my CUNNING to 75, all 15 of my Tepos have "helped" contribute to a mission requirement.
And hey, there's meeting requirements:
You choose which personnel to use to meet mission and dilemma requirements. Any "excess" personnel are not required to apply their skills, etc. toward meeting the requirements.
Emphasis is mine. They may not be required to apply their attributes, but they're not prohibited, either. So why can't my excess Tepos also contribute?
On the flip side, there's this nugget about dual-personnel cards:
(They pool their CUNNING for the "If their CUNNING <15" clause.)
Yes, that's a very specific clause of the glossary, but it could suggest that the Cunning is inseparable from the personnel when meeting requirements. So a Tepo contributing his Acquisition is inseparable from his CUNNING contribution.
