When are show columns expressions calculated?

A question for performance reasons: When are show column expressions calculated?

1. Calculated for every row when syncing, same as a Virtual Column;
2. Calculated when open the view which contains it, same as a Format Rule;
3. A third option that I didn’t realize there was.

Effectively (2), assuming you’re referring to the Content property.

Yes, thats the content property I was referring.

Thank you!
