In to Out Duration in Metadata Display

Bump, because I fear I may have not been clear enough the first (well, sceond) time. This round I will supply the 'why' of what I'm looking for as well as details to what I have thus far tried. Skip the rest at whatever point you understand the question; I do go on.

The Question: Is there a means of looking at a sequence bin and see, at a glance, the marked In to Out duration of the sequences therein? Video Duration from the Metadata Display pulldown has not worked for me.

The Issue: I have a bin that holds my various sequences —cut sequences, not simply clips. Many of the sequences have, tacked on to one end or the other, bars and tone or black or just extraneous scenes I'm not ready to tear off yet. But I'd like to know, without putting the sequence in the timeline, how long the good stuff is. 

How I've done it elsewhere: Typically (in another NLE), I'd have an In-Out heading and would have marked first and last relevant frames last time I worked on the sequence.

Why I care (I find this a ridiculous heading, but I cannot tell you how many times I and others I've followed, have been asked this before someone —someone who's willing to offer suggestions after poo pooing your need— willingly offers suggestions) One, frequently relevant reason I would like an In - Out bin heading is I may not remember if I've gotten a sequence to time. If I marked the sequence last time I was in it, In - Out would tell me it's duration.

What I've considered: 

1. I was told here, Video Duration will display this, but it just gives me the same answer as Media Duration – the overall duration of the sequence and not the marked area as desired (see illustration earlier in thread).
2. Could this be an issue with my old computer?
3. I've restarted the computer and app
4. Am only minor update off up-to-date (v. 13.1.4  vs v. 13.1.5)
5. Have reviewed carefully all previous suggestions

Desired Solution: I hope this is clear by now, I want to know how long the relevant portion of my sequence is by looking at the bin it's in.

Hi Martin,

Durations should be equivalent if you have not yet trimmed your clip. 

Thanks,
