Start with box speed. RPX25 is a really new film, and Diafine is not used by that many people, so you're not likely to get a lot of responses.

I have found that Diafine works great at box speed for all films, and also works well at some higher exposure indexes for other films, like Tri-X.

Bracket to get in the ball-park. Take the same picture over and over at different EI's, and develop the entire roll at once in Diafine. See which exposure you like best, get another roll, and use that speed. Fine tune from there.

I've only used Diafine a few times so far, but like it. Box speed seems to make my negatives a little flat, but they are fine.

Box speed may make negs a little flat, depending on how you meter at box speed. But it is the safe bet with just one roll at hand. I too advocate using more than one roll, and do some basic testing before photographing anything important.
