 Tracing Difference
The thought of difference has actually been more widely developed than the notion of proximity, and it will be shown here that difference is of great importance in 'filling in' for form where form is challenged by proximity.
Derrida's differance bears mute witness to how differance is put into play through a trace, and to what of the trace endures as a crossroads for the different ways the writing is read.
The thrust of the associated notions of difference and proximity is to supersede both sides of the argument between rationalism and empiricism by altering the role and status of form.

 Difference Engines
method of differences is a technique for calculating tables, in which the vast majority of the calculation involves nothing more than simple addition or subtraction.
We see that the general case of an nth degree polynomial requires n differences to evaluate by this method, and that, once we have found the initial values for the first row of the table, the only arithmetical operation required to compute a table of arbitrary length is simple addition.
It is thus possible to envision a machine which holds n columns of digits (to represent n distinct numbers) with mechanism such that on each cycle of the machinery, the number in each column is added in turn to the adjacent column.

 difference. The American Heritage® Dictionary of the English Language: Fourth Edition. 2000.
difference, dissimilarity, unlikeness, divergence, variation, distinction, discrepancy These nouns refer to a lack of correspondence or agreement.
Difference is the most general: differences in color and size; a difference of opinion.
Distinction often means a difference in detail determinable only by close inspection: the distinction between “good” and “excellent.” A discrepancy is a difference between things that should correspond or match: a discrepancy between his words and his actions.

The reason these percentages are different is that they are percentages of different amounts: 40 percent of 5, and 28.57 percent of 7 - both are equal to 2.
When there is no directionality to the difference, so you can't distinguish an "old" value from a "new" value, you have to use the average of the two as the standard of comparison, as in your formula.
This is one of many cases where terms are used differently in various contexts, and what is a minor error of terminology in one question can lead to major confusion for people coming at it from a different direction.

 Potential difference - Wikipedia, the free encyclopedia
In physics, the potential difference is a quantity related to the amount of energy that would be required to move an object from one place to another against various types of forces.
Potential difference is the difference in some quantity between two points in a conservative vector field of that quantity.
In mechanics, the gravitational potential difference between two points on Earth is related to the energy that would be required to move a unit mass from one point to the other against the Earth's gravitational field.

 Edge: THE SCIENCE OF GENDER AND SCIENCE
There are many small differences in men's and women's brains, including the overall size of the brain (even correcting for body size), the density of cortical neurons, the degree of cortical asymmetry, the size of hypothalamic nuclei, and several others.
Intrinsic differences in aptitude are a larger factor, and intrinsic differences in motives are the biggest factor of all.
This pattern of differing profiles is not well captured by the generalization, often bandied about in the popular press, that women are "verbal" and men are "spatial." There doesn't seem to be any more evidence for that than there was for the idea that women are people-oriented and men are object-oriented.

 Soft Difference, by Mirslav Volf
Christian difference is therefore not an insertion of something new into the old from outside, but a bursting out of the new precisely within the proper space of the old.
The focus on the combination of difference and acculturation would assume on the part of the Petrine community, however, a nonsectarian distance from their social environment: one is free from the pressure either simply to reject or simply affirm the surrounding culture.
The difference that joins itself with hardness always presents the other with a choice: either submit or be rejected, either "become like me or get away from me." In the mission to the world, hard difference operates with open or hidden pressures, manipulation, and threats.

 Keirsey Temperament versus Myer-Briggs Types
The second essential difference is Myers used a linear four factor model to characterize "invariant" patterns of behavior of the individual throughout their lifetime, whereas Keirsey uses a systems field theory model to characterize these patterns.
One of practical problems with the defining the difference of the models is a great deal of printed or web material and books have mixed the two models together: for they are similar.
The difference between character and temperament (or type) of the personality help distinguish between what 'changes' and what stays the same, this is true whether one uses the Jung-Myers notion of archtypes or function types or Keirsey's notions of character and temperament.

 A Difference Engine Built With LEGO® Pieces
Because of engineering issues as well as political and personal conflict the Babbage Difference engines construction had to wait until 1991 when the Science Museum in London decided to build the Babbage Difference Engine No.2 for an exhibit on the history of computers.
A Difference Engine uses Newton's method of differences to evaluate a polynomial for successive values of x; 1, 2, 3, etc. Computing the next entry in a table can be significantly easier than computing an arbitrary entry of the table.
In simple terms the method of differences is based on the observation that if the work has already been done to multiply 5 by 6, that work can be reused to multiply 5 by 7 with the addition of another 5 into the previous total.

 Difference Between a Metaphor and a Simile.
etaphor and simile are quite different, but are commonly confused simply because they are so very similar in nature.
Though some have argued that a simile is simply a weak metaphor, it is difficult prove with certainty in world of ambivalent usage.
In the end, it may one day be determined that the difference between true metaphor and true simile may well be regional within the brain, with metaphor rooted in logic and the simile rooted in emotion.
