OBP6 is simply the percentage of competitors your horse has beaten in its six most recent outings.
How to calculate it:
- Only include events where you started XC.
- If you started XC but didn't finish the course or the competition, that competition still counts but the number of opponents you beat was 0.
- Anyone who started the dressage phase with you counts in your total number of opponents faced.
- 6 previous competitions is ideal, but you can work with as few as 3.
