Per Instance Memory Usage vs Main Component

Hi everyone -

I’m in the process of investigating the cause of a major memory issue in one of my more robust prototype files and had a question about the memory usage per instance of a component vs the memory usage of the main component.

**For example, if I have: “Component A” using 0.4% memory as the main component and there are several variants within Component A…

…does that mean each instance of Component A (regardless of which variant is selected) will also use 0.4% memory or are instances a fraction of the memory usage of the main component?**

I am also curious if anyone can verify my assumption that when checking the option to “Show Memory Usage in Layers Panel”, layers with " – " instead of a percent value are using less than 0.1% of memory?

Thank you for any assistance!
