Let me explain my little knowledge about that

here's the helpful method I do as a curator on steemit
if you upvote 0 minutes after the Blog Posted. 100% of the Upvote rewards will go to the original poster
if you upvote 3 minutes after the Blog Posted. 90% of the upvote rewards will go to the original poster & 10% will go to the upvoter(you)
if you upvote 15 minutes after the blog posted 50% of the upvote rewards will go to the original poster & 50% will go to the upvoter(you)
if you upvote 27 minutes after the blog posted 100% of the upvote rewards will go to the original poster & 90% will go to the upvoter(you)
if you upvote 30 minutes after the blog posted 100% of the rewards will go to the upvoter(you)
here's the simple logicso if you want to help the blogger to earn more without gaining in return much better to upvote his/her post 0 minutes after the blog posted
if you want earn more much better to upvote Post after 30 minutes
note: you can earn more depends on your 'steem power' hope this help
