Interesting, John!  I think that Ancestry used to label the matches with a confidence level, but that location on their page now gives the opportunity to select maternal or paternal side and the paper-trail relationship.

In the meantime, lots of amazing work was done by 

Blaine T. Bettinger www.thegeneticgenealogist.com 

resulting in useful charts and tools such as this one: https://dnapainter.com/tools/sharedcmv4

And then Ancestry riffed off of that to show the probabilities in a percentage, visible when you start to enter your actual relationship with the DNA match.  

So we have much more detail available now on the likelihood of the relationship we think we have resulting in the amount of shared DNA we see, much more granular than a confidence level.

Thanks for mentioning it; i think i might go back and adjust my 'DNA confirmed statements', and as you point out, maybe our Ancestry template here could be updated as well.

Thanks for bringing this up!

Cheers
