Someone was explaining that ultimately you will wind up with more if you have it set on 50%. I can't remember who said it, but you may want to look into this more and ask someone who really knows about this info. The person who said it really understands how things work. Just want you to be able to accumulate the max. I just try to search for things that interest me and upvote. When I run out, I just comment. I might go back another day to upvote when I have more to give.
Thanks for your post.
