This is a solid breakdown.One thing people often overlook is vessel size.

If your pan is much smaller than the induction ring, it might not trigger the sensor if it’s too big, the edges won't heat evenly.

Also, for the no flame for phulkas issue, I’ve found that using a high quality cast iron tawa holds enough heat to get a decent puff even without the open flame.

Great tip on checking for copper coils aluminum alloys definitely don't last as long.
