When all of the scores are within one point of each other, or evenly distributed, you are one of the rare few who are "Tri-Doshic". When you have this mind/body type, you are more likely to remain in balance, because the ratio of Vata, Pitta and Kapha is nearly even. You will tend to have lifelong good health and a good immune system. However, whenever you do get out of balance, you must work harder to balance all three doshas, because you don't have a "lead" dosha to start with.
Sometimes it's hard to figure out some of the answers to the questions, and in that case, your body type may be obscured by a Vata imbalance. Vata is the lead dosha, and can oftentimes present like Pita or Kapha. For example, you may be small-boned, but overweight. A Vata imbalance could very well cause such confusion.
The doshas like to move around, and there are hundreds of ways that they relate to each other- so to be in equal ratio at birth is highly improbable. You may actually be a double-dosha type after all. The most important thing to remember is not to try to fit yourself into a particular category, but to learn as much as you can about yourself.
The Tri-Dosha needs to look more carefully at keeping in balance with the seasons and the clock, and seeing how each particular dosha expresses itself in the mind and body. Look at which dosha is dominant in the mind section, and which dosha is more dominant in the body section. You probably have qualities of all three doshas, and you need to find ways to keep in balance that go with the seasons, too. (see the article on the calendar and the clock)
