D/T grid
The D/T grid is also known as the 'Fizzy grid'[1] and it is a matrix with all the 81 possible D/T-combinations a geocache can have.
In Profile Stats and the statistics at Geocaching.com the color of the cell of each grid changes as the number of caches in the cell increases, this is true for both the 366 grid and the D/T-grid. At Project-GC the "final color" is red[2] and this will be the color of the highest number on the grid, the other cells of the grid change with every found on the grid and are relative to the scale between green[3] and red.
A common goal is to fill the D/T-grid with at least one cache for each cell, doing so multiple times is generally referred to as "looping the D/T-grid". Below is an example of a D/T-grid with 3 loops.

The D/T Matrix Tool helps you plot a map of all geocaches that will fill an empty slot in you D/T grid.
The D/T History tool can help users with a paid membership find some caches that have had their D/T-rating changed. This is helpful if a user finds that they have "lost" a loop of the D/T chart.
