Question about densities in calculations

[Jackof_noTrades068]

Say character X creates a planetoid that has a stated mass of 3 Solar Masses and is 8km in radius but is not a black hole (not quite)
Then I calculate the density to be a specific value

Then Character Y uses Character X’s same power to creates a planetoid that is 900m in radius

Would it be allowed for me to use the density discovered for character X to calculate the mass of Character Y’s planetoid?
Or would that be be considered Calc stacking?

Very specific question I know.

No, because you cannot guarantee that the density for planetoid Y is the same as the density of the planetoid that X created.

I'm p sure you should be able to calculate density regardless, especially if the said power has a stated for mass for the things it creates

Our calc stacking rules aren’t as clear on stuff like this, but at the very least it would need to be a situation where the density can’t have changed.
So for instance, if the power is to create a specific fictional material that’s noted to be super dense/heavy, and that’s why it has such a high weight, and there’s nothing going on such as pressurizing or compacting the material that could effect the density, then this might be okay.
On the other hand, if it’s something like taking a bunch of material from the surroundings and crushing them together, you can’t guarantee the original materials have the same density, or the new material has been compressed to the same extent, so this wouldn’t be allowed.
