Percentage Calculations

Therese are notes from the Scribes page about the following Special Ability

Percentages for units that increase by a given land percent do not have to be exact. For example, if the bonus is +1 for every 10%, then the unit still gets +.1 for every 1%, +.5 for every 5%, etc etc. Units above are listed in terms of the percent that will give the unit a whole number, but actual unit powers are calculated based on exact land percentages.
