FWIW, I ranked some of the things in that survey that are important for me.
1) She can create a comfortable close embrace.
For me, this is easily the most important factor (at least with most tango songs). Especially when dancing to something like a slow Rodriguez, Tanturi, D'Agostino, etc., if the follower doesn't give a good embrace, I won't be in a hurry to dance with her again on a song like that. BTW, I've had two unforgetable tandas (because the embrace was really bad) with teachers. It's very unlikely that I'd ever take a class from them again.
2) She follows what I lead, as opposed to trying to back-lead me.
I must say that I have bought into the concept (or philosophy) that no one follows anyone. You try to dance together. I indicate my intention, and I'm hoping she will come with me, and at the same time, I'm trying to accompany her. If she's got her own agenda, it can be annoying. However, there are the rare few who can pull this off and still keep things very enjoyable.
3) She follows very well, even though she’s only a beginner.
This is pretty much in line with the previous one(s). Have a nice embrace, stay with me, and step on the beat. That's all I really need. If you do those things, I'll be very happy (at least with most songs). BTW, to me, following well means staying with me (in the embrace), and at the same time, not making me have to do too much to indicate my intention.
4) She has been enthusiastic dance partner in the past and she is happy to dance with me.
Yeah, I'll admit that people who make it known that they want to dance with me are preferred over ones who don't make it so clear. Also, people who are simply nice (and friendly) to me have an advantage.
5) I’ve seen her dance before and I know how her dancing is.
Yeah, if I know she's a good dancer (by my criteria, not some one else's), then I'd like to dance with her.
6) She has generally good hygiene.
While this is a factor, it's actually not a deal breaker. If you are OK on more important factors, this gets overlooked. Actually, there are only a handful of women where I've even noticed (in a negative way) their hygiene or perfume.
7) She has declined my invitation in the past on several occasions.
BTW, this is in no way, shape, or form about revenge. I just don't see the point in wasting time with someone who doesn't seem to want to dance with me.
