I recently made a slider in React/Redux. Imagine a slider that has a width of 200px but needs to report values from 0 to 100. (The width is governed by external factors, e.g. other sliders nearby that need to report a widger range, but must visually be of the same width.) This means that sometimes you may move the slider just by a pixel and need to register the movement, but the underlying value won't change. I.e. you have the slider offset and the actual value.

The slider offset is a very transient variable that is not really important. Next time you load an object from the database you'll just convert the value to a slightly different offset and nobody will notice. Are you going to store the offset in the big store?
