Allow me to translate:
We could detect brownouts by measuring current and voltage.
And please excuse my bluntness, but the rest of it is entirely superfluous and ridiculous. Seriously? DVBST? Rogowski coils? Hand trimming shunts?
This is the PID show all over again. Inspire students. Don't try to impress them.

I don't need to impress anyone at all. It has no impact on me either way...what so ever.
1. There are lots of kinds of coils, and even field measuring coils, I'm being specific about which one.
2. There are other ways to measure current, I'm being specific about why this way.
3. I had stated concerns about why a shunt resistor to measure current with Ohm's law was a bad idea in this case before (availability), I am adjusting my view based on the available materials.
4. I was looking for an even more simplistic and cheap way to get to this goal of this brown out detector, and I had hoped to seek out specifics so I was seeking the limits of the problem. Hence why I considered how an analog storage oscilloscope is made (it's a DVBST tube).
5. I provided an alternate example of how others solved this problem, using a robot that was targeted specifically towards an educational setting.
Further, for anyone that actually wants to know what those terms mean...

We need to solve the problems and I am trying my best to find a cost effective way to do that with the help of these mentors in the spirit of community contribution.
Thanks.
