Fair enough on the first point!

The interesting scenario re: Polaris A's age would be if a larger, younger original star merged with a smaller, much older star. You'd have a small amount of late-stage byproducts in an otherwise relatively early-stage star. That would definitely make any age models 'confused' heh

I could imagine a scenario where the math works out such that the star appears a lot younger than it is despite being the product of a merger of two older stars, based on the masses and ages of the contributing objects and the amount of different material contributed by each
