How Compatibility is Measured. What if only 1 soulmate match?

Every birth year has a different number of perfect compatible birth years. The dog only has one compatible birth year. The rabbit has I think five or six perfectly compatible birth years. 

The same applies for enemy years. 

And the same applies for months.

If you have three compatible birth years you also have three compatible birth months.

So depending on the sign they enter everyone will get a different result. And we need to show the perfectly compatible year and the perfectly compatible month. 

Because when the two intersect, the compatibility becomes exponential. Instead of just being twice as compatible, they become 10 times as compatible. If the birth date is also compatible, then they're compatibility is 100x
