Everything is set to 95 same as orginal Fallouts.
I've never bothered to try to change the 95% limits, but I'm pretty sure it's hardcoded. From the scripts, it seems when something is not capped at 95%, the devs usually made an explicit note.
Radiation Resist it's capped to 95, but i can't find in radiation.fos something about " 95 " or anything related to this cap
