Re Amber : I think it wasn't such a bad choice. She can be nervous of course but when she is on, she is capable of beating all the top skaters as she has done in the past at both her own Nationals of GPF.
So, getting an extra program may help her settle her nerves for the individual event. Putting trust in her, allowing her to earn a gold medal, even with an imperfect skate, is huge for an athlete who sometimes deals with nerves.
Also, it was much more important to have Alysa skate the SP, where a bad performance is much more costly.
