I wouldn’t count on the gdc at all to fix the auton scoring rules by then, if they haven’t done so in past month I find it unlikely that they’ll do so in the next few days. We can hope, but don’t bet your event on it.
This is probably your best bet to try and convince event staff to follow the manual scoring rules instead of their own, but their decisions will ultimately be out of your control, and if the rules aren’t clarified by then I hardly blame them for sticking to their interpretation.
The best thing you can do before that to prepare is to write multiple auton routes for the different sets of scoring rules they could possibly use. If they follow the manual exactly, you’ll only gain points from rings in alliance goals so you should have a program that does that. If they allow neutral goals to count as well but not platforms, you might want an auton that grabs neutral goals and takes them into your home zone. If they count all methods of scoring towards auton, parking with a goal is probably the best way to win auton.
What the gdc is essentially doing here is forcing competitors to make an array of auton routes to compensate for the wildly different ways events will be scoring autonomous if they want to be able to win auton at different events.
