I think @centerlink's vote is 25 minutes after the post. I'm pretty sure ausbitbank's auto vote is before @centerlink, just don't know exactly when. On the curation trail better to set the time to 0 so that you will vote straight after @centerlink voted.

If you using the "fanbase" feature on the steemauto... you can experiment with 15 - 30 minutes
