How does it work?

1. The default rule is automatically created and saved in the Rules board when an attribute is matched with a value. 100% of the products are immediately impacted. 
Examples: 
- I completed attribute "quantity" with value "10". 
- I matched attribute "quantity" with my field "stock".

2. When a rule is created, it is automatically placed above the default rule. The rate of products covered is immediately re-calculated. 
Example: My rule #1 is impacting 75% of my products. Therefore, my default rule only impacts now 25% of my products.

3. Then, all new rules will be placed above one to another, and the system will re-calculate the rate of products covered.
  
Example: My rule #1 was impacting 75% of my products. Now that I have added a rule #2, the rate of product covered has been re-calculated. My default rule does not impact any products anymore as my other rules already are impacting 100% of my products.

IMPORTANT: The calculation of the impacted products works as a funnel all the way down to the default rule. The more rules you add, the fewer products may be impacted in the default rule.
