A2.1 specifies that a boat's score shall be the total of her race scores excluding her worst score unless something different is stated in the NoR or SIs.
I have seen the following wording used to change this: "When seven or more races have been completed, a boat's series score will be the total of her race scores excluding her worst score."
I think that we all understand that the intent of this statement is to mean that a boat's worst score will not be excluded if less than seven races are completed. However, I don't see how the wording of A2.1 allows this without explicitly stating that no score will be excluded if less than 7 races are completed. Am I missing something?
