I guess Yume and Mahiru get PR while Kirara and Lily get SPR doesn't mean what…just to balance SPR and PR in part 1…Mahiru will undoubtedly win s4 but she only gets PR…

So the chance of Yume and Lily win is equal, either Yume wins s4 but Lily decided create SPR or Lily wins to reach her goal to create SPR eventually, and Yume is allowed for creating PR and brand.
