Thanks! I don't feel that I am a contributor, but thanks very much.

This is great. I have to play a around with it a bit but it looks
*precisely* what I was looking for since quite a while.

I have to admitd that the complicated structure

#+TBLFM: $2= "nan"="$1" ? string("NP") : 0<=$1 && $1<=4.9 ? string("SS")  

I would have never found myself.

Thanks very much. Again I have the feeling that this is a real world
example worth to be mentioned in the documentation (such example make
your package so much more attractive because I presume most users feel
like me, they are overwhelmed by its potential but on able to really use
it). But maybe I am a bit biased :-D

I have not looked into your second part of your answer since the first
seems so useful.
