How do you know if your horse is 1D, 2D, etc? What does that mean?
If you are running at a barrel race they are typically called "4D" races, at least around here. There can be some that are simply "3D" or as much as "5 or 6D"
Lets use 4D as our example.
Say you go and make your run and you run a 16.325
Now the fastest time was a 15.258, so that person would win the "1D" division and set the pace for how the other divisions are paid.
Example: 1D Division 1st place: 15.258 (from there the next fastest time would be in the 2nd place slot) 2nd place: 15.266 3rd place: 15.344
2D Division (add .5 seconds to the fastest time and that will be the winner of the 2d) 1st place: 15.758 2nd place: 15.766 3rd place: 15.844
3D Division(add 1 second to the fastest time) 1st place: 16.258 2nd place: 16.325 (your hypothetical time) 3rd place: 16.447
4D Division (add 2 seconds to the fastest time) 1st place: 17.258 2nd place: 17.336 3rd place: 17.587
****Some places choose to run the 4d with whats called a "half second split" vs a "whole second split" and this just simply means that instead of adding a full two seconds to determine the 4d times you would add 1.5 seconds****
some groups will place down quite a few slots depending on the amount of runners.
