Thanks very much for this input. I will definitely post on it once i simplify it down!!

Here's a little bit about you 7 day confusion : The original post was more than 7 days old and has paid out, so even if you upvoted on that you wouldn't get any curation reward. BUT...BUT BUT BUT.....But you did not upvote, you COMMENTED. Your comment is a NEW POST now!! The authou upvoted on your COMMENT which is an active post now (for the next 7 days). So any upvotes you receive on that COMMENT you will receive author rewards on that, and the people who upvotes on that comment will receive curator reward because, even though the original post has paid out and not active anymore, you comment which is a fresh post, is technically active.

This is how I understand this situation. I'm not an expert, but i'm just trying to be logical here. Hope this answered your question!!
