Rank I should provide: +0-30 Max and Current All Power Levels
- fact is: +0-27 Max and Current All Power Levels
Rank II should provide: +0-40 Max and Current All Power Levels
- fact is: +0-36 Max and Current All Power Levels
Rank III should provide: +0-50 Max and Current All Power Levels
- fact is: +0-45 Max and Current All Power Levels
So either fix the Description or the Mechanic.
I made a Note on Gamepedia for this.
