I honestly don't think anyone has an actual proven measurable scientific answer to your question. All we have are subjective theories about what we think logically is supposed to happen. This is why we need more funding for lab research and we're getting there but I'm affraid it will be a few years for that.

Logically I would assume that a late harvested Sativa would mimic the effects of an early harvested Indica, but who knows. Good luck on your quest for actual proven answers.
