You may have to repeat the question loudly. Try turning it up to 11.
Vixen is quite happy with the notion that ′
always indicates feet and ″
always indicates inches, and that we can omit the unused, unnormalized yards because these two symbols are unmistakable for length measurements regardless of any variation in context. She is correct there.
But when notating time duration using the same system, she insists there is no similar rule. (Hint: there is.) She claims that for time duration, ′ can mean either hours or minutes, depending on context, and that ″ can mean either minutes or seconds, depending on the same context. The notion of context she advocates is that the reader is just supposed to know what duration of time would be compatible with the value stated. So a statement,
John finished the race in 4′ 33″.
obviously means the race was for a mile and John ran it in four minutes thirty-three seconds, because that would be a reasonably understood context. Except that the race was actually a marathon and John ran it in four hours, thirty-three minutes, and the notation is exactly and ambiguously unchaged. Vixen hasn't explained how seconds would be notated in that case under her foisted vernacular usage.
For someone to state that Cage's innovative avant-garde musical piece is implicitly understood "from context" to last only four minutes and thirty-three seconds—because the context is a musical piece and that's a reasonable inference for the duration of a musical piece—simply means the person hasn't attended a Wagner opera before. We know the notated title is properly pronounced, "Four minutes, thirty-three seconds," not because there is some ineffable context at work here, but because ′ always means minutes of time and ″ always means seconds of time.
The attempt to interpolate vague contextual clues is merely more evidence that Vixen is out of her element when it comes to all things technical. She says context is all-important. That is exactly the opposite of the direction in which technical standards have pushed for the past century. What's all-important these days is for units and symbols to be unique, standardized, and unambiguous.
