I think the strength property is useful for defining the relative strengths between elements. The strength property is not for setting an absolute strength since it's hard to measure and depends on the user agent, system settings, what technology is used for providing the actual feedback etc. Instead, the user agent should (when possible) implement the strength so that 'weak' is noticeably weaker than 'medium' and 'strong' is noticeably stronger than medium.

I think the names you suggest for the property and the values are definitely not bad. Let's discuss the naming more closely if the proposal is otherwise approved.

Thanks! These are fixed now.
