Interdimensional variance is a key mathematical parameter, used in the Interdimensional Shifting model, popularly known as the Warped Bubble Wrap model. It is a multidimensional array which defines the distance between reality source and a dimension, as well as the angle. Both distance and angle can predict dimension type with high degree of certainty, as well as funnel side effects.
Interdimensional variance can be measured with the help of the Exotic Portal.
