As I mentioned above, I put it in the SIs. Some OAs and judges feel better if you include verbiage about the purpose is to allow more racing. I don't like to see statements like "after 50% of the fleet has finished..." because sometimes you need to kill people well before anyone finishes (picture W/L with a mid-course S/F line and an 80-boat Opti fleet, mixed bag of "haves" and "have-nots." The most fair place to finish them is at the last top mark, sometimes the leaders aren't quite finished yet, and you have 4-5 boats still going to the weather mark.
