I have my own Excel for most Divina cards dividing their efficiency ratios into ATK and DEF, but I use a base of 1 spirit : 300 ATK/DEF. So unless everyone gets on the same page and uses the same standard for efficiency, there might arise problems related to how one translates or interprets efficiency ratios.
