"WEEKLY LIMIT" did not exist until very recently. It has been set at 2 for everyone. You need to change it if you want to support an author more than twice a week. If you don't you might lose out on curation rewards.
But while you're at it, I would like to recommend that you add new authors as recipients of your auto-votes.
At this point, I might as well let you in on a little secret. The most profitable targets of auto-votes are not the guys who receive massive total rewards per post. Why? Because so many others have got the bright idea of going after these seemingly big fat targets. Hence, when you auto-vote these authors, you'll end up sharing your curation rewards with a lot of other curators and if you try and front run everyone, you end up forfeiting a lot of your curation rewards as early upvote penalties.
It's a lot smarter to take the trouble of finding authors who are regularly upvoted by far fewer authors but whose content you like. Those users provide better targets for front running the bulk of the vote mass regularly landing on their posts. It's far better for you and the platform as a whole to concentrate your voting power on these authors. User retention has been a serious problem for Hive/Steem for a long time. Making it easier for good content creators to find support sooner will help user retention.
