New LSAC GPA Rule - Should I Wait a Year to Apply?

I have a question about the new LSAC GPA policy that's supposed to take effect for the 2027-2028 application cycle and whether it would make sense for me to wait an extra year before applying. I attended a 5-year Collegiate Academy program where I took courses at a community college while still officially enrolled in high school. I was originally supposed to graduate high school in 2024. But because of the program, I stayed an extra year and officially graduated in 2025 with my associate degree. During that time, I was on a biology track, and the grades that are pulling my GPA down are mostly from those science and math courses. I eventually realized biology wasn't the right path for me and switched to economics. Since switching majors and attending university, I've been performing much more consistently and haven't gotten anything lower than a B. If I apply this cycle and all of those community college grades are included, my LSAC GPA would likely be around a 3.3 to 3.4. If I wait until the 2027- 2028 cycle, when those high school-earned college grades are supposed to be excluded, my GPA could be around a 3.8, assuming I continue doing well. So my questions are: First, since I didn't officially graduate high school until 2025, would those community college grades earned before graduation be excluded under the new rule? Second, is that implementation date firm or could LSAC delay it again? Third, if I apply this cycle, would an addendum explaining my major change and the upward trend realistically help, or would that 3.3 to 3.4 still put me at a big disadvantage? And finally, given the choice between applying sooner with a 3.3 to 3.4 plus an addendum versus waiting an extra year and potentially applying with around a 3.8, what would you do? I'm trying to figure out whether the addendum and upward trend makes applying sooner reasonable, or if the GPA difference is big enough that waiting a year is the smarter move.
