From my experience so far as a musing user, musing isn't really concerned about your number of upvotes before you can get upvoted by musing.
Just as you've explained, a post with more upvotes from their Steemit followers may appear to be the first in rank but that sometimes doesn't guarantee their full upvotes by musing. I have seen cases whereby a user had upto 13 upvotes from his Steemit followers which made him appeared on the first rank in the answer but he wasn't upvoted by musing because his answer lacked quality. A user below him with 3 upvotes initially was able to make it to musing trending page due to the quality of his answer.
The fact is you have to provide quality answer because musing is a free from cheating as the curators are doing their jobs to the fullest.
It may serve as luck for some users who are chance to gain upvotes from their followers which made them rank the first place in the answer platform because the curators may think that for such person to have that kind of upvotes, he or she has came up with quality content.
Please let's try as much as possible to provide quality answers and also note that you may not even get upvoted for providing quality answer everyday because the platform also have to be considerate of others.
Thank you for reading and I hope answers your question.
