The tag [functional-strength] currently has no usage guidance. One may imagine that this could be because the phrase's definition is not well established.
One can find numerous discussions on the web debating the validity and usefulness of the qualifier "functional" in the phrase "functional strength". Some people believe the qualifier is meaningful; others find the phrase redundant.
Regardless of lack of consensus, the tag would have a purpose for this forum if it is definably separate from other related tags such as [strength]. Conversely, if no such separation can be defined, the tag's existence does not seem warranted.
Can the [functional-strength] tag's usage guidance be written? If not, would it be of value to consider removing or merging it?
