Clarification Needed: Homogeneous Object HP Calculation in Supers vs Basic Set

[Werethunder]

Hello fellow GURPS enthusiasts,

I've come across a point of confusion regarding the calculation of hit points (HP) for homogeneous objects in GURPS Supers compared to the Basic Set... I'm hoping to gain some clarity or insights from the community.

In the Basic Set (p. B558), the formula for calculating HP of homogeneous objects is given as 8x the cube root of the object's weight in pounds. This implies that homogeneous objects are quite sturdy (even compared to machines).

However, in Supers (p. 76), the method for calculating an object's cover value (which involves HP) suggests dividing the HP of homogeneous objects by 4. This seems to indicate that homogeneous objects are less sturdy in super-powered scenarios.

This difference leads to a confusing situation where a homogeneous object like a rock or a tree trunk appears more fragile in a super-powered context than in a regular one, which seems counterintuitive.

I'm looking for clarification on this point:

1. Is there a specific reason for this difference in HP calculation between the two books?
2. Should the Supers method override the Basic Set in superhero games, or is this a case where GM discretion is advised?
3. Has anyone else encountered this issue, and how have you resolved it in your games?

Any insights or explanations would be greatly appreciated. Thank you in advance for your input!
