It is worth making one final comment, since it is past the seven days I can't edit the post directly. Extending section 2, if the small steemian you're autovoting receives too large of upvotes from a supporter, i.e., DTube or another curation project, then your curation reward again will be tiny. I've found my curation payouts have frequently been destroyed by DTube because they upvote with too much power for someone with my limited SP to compete against.
