The plea for data is good, but the main point of the rule is not to reshuffle the podium at the end of the contest, but to change the experience of flying the contest. For that, we can't simulate or re-score, we need to try it.

That's why it's available, as an option, at regionals. The RC does its best to evaluate new ideas with available data. But then you have to go try it, collect some new data, and see if it works, where the bugs are and if people like it. (Last start rule is also there in the same way.)

Pilots who like the idea: Implore the CD / CM of your upcoming regional to declare worst day adjustment for your regional, and announce it before preferential entry deadline so that the pilot's meeting doesn't have to be a long contentious matter.

It is only fair to pilots who don't want to try it to let them know ahead of time.
