Infographics are good for Pinterest but not for quoting...

Basic rule of thumb to earn best rewards is to vote approximatively 15 minutes after the post has been created or later.
Look For:
High Dollar: $$
Low Vote Count: 7 votes

High payout surprised me! I have read a few about the reward efficiency, notably https://steemit.com/steemit/@jga/author-and-curator-rewards-in-hf19

I concluded:

• If you are the first voter on a post, you will reach 100% vote efficiency if the payout is worth 15 times the value of your vote
• If your vote is worth a few, the relative incentive to vote a post before the end of the penalty time is
  sqrt ( final_payout / current_payout ) * minutes_elapsed / 15

If you vote early on a post that will reach a high payout, the popularity can counterbalance the time penalty, and your vote will have a good efficiency.

I guess your strategy is different:

• A post which has already a good payout after 15 minutes is in the Hot selection and will soon be in the Trending one. It will land on the moon, your curation reward too.
• It is necessary to wait 15 minutes that all the first people voted to evaluate what will happen next.

Note that if everyone votes after 15 minutes, a vote after 14 minutes will beat them all.
