The D/T grid is also known as the 'Fizzy grid' and it is a matrix with all the 81 possible D/T-combinations a geocache can have. Similar to the 366 grid the color of the cell of each grid changes as the number of caches in the cell increases. At Project-GC the "final color" is red 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 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.
Top unique DT combinations in one day is a top list for unique DT combinations in one day.
Top Number of Loops of the DT Chart is a top list for number of loops of the D/T grid.
The D/T Matrix Tool helps you plot a map of all geocaches that will fill an empty slot in you D/T grid.
