That might work for Tier 1 or Tier 2 girls, but if you want the Tier 3 girls, you'd never be able to get their outfits during the event due to such long fake times after each reset. It's better, if you ever reach the twins, to just play it out. Plenty of time during the event to get all outfits IF you've reached all girls, and if not, there is even more time for you to get the outfits for the girls you already have. No need to rush.
