Do updates to ratings trigger date_modified for constituent records?

Documentation is somewhat conflicting/difficult to interpret:

https://developer.blackbaud.com/skyapi/docs/in-depth-topics/api-lists

"The following fields have the potential to update the date_modified value on constituents, without user input:

• Age increments (ie: a constituent has a birthday and their calculated age is one year older)
• Wealth ratings are updated (occurs once a year)"

…to me, this would indicate changes to wealth ratings would trigger date_modified on constituent records….

But then the next paragraphs:

"And the following fields may trigger an update without the changes being reflected in the API, as the correlated fields are not surfaced on the Constituent entity today:

• Solicitor status change
• Prospect classification
• Wealth ratings
• Appeals"

Can anyone clarify?

Thanks,

Allan
