The team decided to put the same rules on curation as Steem is doing it and calculating the relevance from it. Under Steem you will get penalized in your curation if you vote within 30mins after the article has been posted. (Under HF19, it will change to 15min under HF20) If you vote within 30 min. You will get almost no curation reward but the Author will get it. (Also this will change with HF20 as it will be redistributed into the curation pool).

Easy explanation for you.

• Vote as early as possible with a high voting weight, but after 30 min. of posting the hunt. -> That will increase your chance for a higher Curation Score (same as with Steem)
