I might like to mention that a couple of skills in DFO have faulty descriptions. What you see as <decimal 1> is MOST LIKELY a shortcut line to the skill file itself. In the unpacked files, skills are separated as the description text and the actual skill file. The description, from what I've seen, uses commands like that <decimal 1>, leading to the skill file with the correct input (such as it recognizing that you have a level 4 Physical Critical Hit, therefore it should properly state that level 4 = +4% critical hit rate, so it will show 4 where <decimal 1> is).
Not exactly fail translation as much as it's a mistake in coding. That's what I believe, at least.
