Dektol 1:2 for 2 minutes seems like normal print paper development time for me in my own darkroom work. The Sprint paper developer I am using is nearly identical to Dektol.

Maybe that's where the difference is coming in. I'm going to scan these negatives right now...
If you consider for a minute that what you suggest would darken my paper negatives a bit, that would then mean that they are even faster than ISO 25 at my current exposure.

What do you think about that?
