I will start by saying that what most of I'm what I'm going to say isn't new and that some of you might already see it this way, but I still feel like this is worth posting. This is a way of viewing the functions that I think is more fitting then using "Valued" and "Strength" as terms to describe the functions.
I think "expressed" should be a term used to describe valued functions and that "focused" should be used to describe strong functions.
The terms valued and strong are a bit off IMO. Calling verbalized functions "valued" functions implies types hold philosophical attachment the element, when this isn't isn't always the case. For example, it isn't totally unheard of for some Beta NFs or perhaps even some LSIs to take philosophical or political stances against pre-mediated violence/aggression, despite "valuing" Se. Rather, verbalized functions are expressed in the actual way a type behaves and communicates, and not necessarily their code for how they think people should behave (Something a Ti "expresser" would likely have). Basically, these are the functions that leak out in face-to-face communication.
I think the term "Strong" is also bad. It implies types are innately better at anything that pertains to the element, when in reality we need to learn how to use elements to their full potential just like anything else in life. In my view the "Strength" from the Ego/Id functions comes the level of attention and study we give them, hence why I think calling them "focused" is more appropriate. Focused functions are generally seen as the elements we must become proficient at in order to survive and operate in the world, while "unfocused" functions are either seen more as games (Super-Id) or all together unimportant (super-ego).
Basic description of the functions using this:
Base: Very Strongly Expressed, Very Strongly Focused
Creative: Strongly Expressed, Strongly Focused
Role: Weakly Expressed, Weakly Focused
Vulnerable: Very Weakly Expressed, Very Weakly Focused
Suggestive: Very Strongly Expressed, Very Weakly Focused
Mobilizing: Strongly Expressed, Weakly Focused
Ignoring: Weakly Expressed, Strongly Focused
Demonstrative: Very Weakly Expressed, Very Strongly Focused
