## Diminishing returnsEdit

Avoidance stats suffer from diminishing returns ("DR"), meaning the rate of return for each point contributed from gear is not constant. The in game tooltips will show the undiminished value, but the amount actually received is lower. Base stats and talents are not affected by DR, but stats from gear are diminished.

The basic formula to calculate the diminished part of a stat is as follows:

 $d = \frac{b \cdot c}{b + k \cdot c}$ $d = \mbox{Diminished value}$ $c = \mbox{Cap of stat, which varies by class}$ $k = \mbox{Coefficient, which varies by class}$ $b = \mbox{Base amount of the stat which is modified by DR}$

(Note that standard algebraic operator precedence applies to the denominator. Multiply k by c, then add b.)

## Class specificsEdit

These coefficients and were calculated by Whitetooth, the author of RatingBuster and TankPoints, primarily through his own personal research and research found on the ElitistJerks forums.

Because dodge contributed from agility suffers from DR, and base dodge varies per class, these are shown as well. Avoidance stats from spells and talents do not suffer from DR, including dodge contributed from base agility.

Classes that show no parry cap are classes that do not have the parry ability.

"Lv80 Dodge%/Agi" is the undiminished rate of "percent chance to dodge" contributed for each point of agility.
