some papers have an iso of 25-50 believe it or not ...
paper is funstuff ...
if you process it in exhausted print developer you can control the contrast more.
i process all my paper negatives in 2 baths. 1 is print developer, and one is a coffee based developer.
they come out great. the thing to also think about is that what looks good as a paper negative
might not look good as a film negative. paper negatives sometimes look "thin" whereas film negatives have some meat on them.
have fun !
