KH: &
Pretty much sum up what the guide has to say. They mention "hit points" and "ability points" once, page 14, and then refer to it as HP and AP. From the instruction manual: Hit Points and Magic Points (pg. 6); Ability Points (AP) [pg. 12]
Days: What you currently have on the stats page matches the guide.
KHII: I'm only seeing abbreviations in the Bradygames guide. However, in the instruction manual on page nine they have: "Hit Points (HP), or health; Magic Points (MP)." For AP, I'm seeing only the abbreviation.
Re:COM: Instruction manual: I'm only seeing abbreviations for CP. Page 17: "Dark Points (DP)"
