Another miles/points values question
 

After having a member turn down a trade offer, I would like to learn from this so I present this question:

In regard to miles/points for the three programs with an active interest on my part, is the following VALUE ranking correct or am I missing something?

1. United MP 12.5 k
2. US DM 12.5 k
3. WN RR 15k

And, does the word "orphan" devalue miles/points just by using the reference?

Thank you in advance for replies. :)
