Great question! Tomorrow I'll have an even more thorough and complete curation trail report. This has been taking me a few days longer than expected to compile all the data and make graphs for the data. Sorry for that as the report detailing this already has to be updated and better explained from days ago . So the @dynamicsteemians has an account on Steemit that has about 3 steem power and what it does is that it votes at times best suited for curation on individual accounts based off options selected in Steamauto and past upvotes for each accounts post history. When @dynamicsteemians votes it is the lead voter for the curation trail. Now most people on this Trail has steem power of 5 to 50. When in steam Auto you follow a curation trail like ours you're given the option to vote after a certain time that the lead trail vote account votes. In this case with the @dynamicsteemians curation trail, you are not having your curation taken by the lead voting account and can vote at 0 minutes from its vote in order to maximize your curation rewards. You are also being followed by curating accounts with bigger upvotes. You dont want to vote after bigger votes and you want to vote with the group to maximize curation. If your vote has a certian value I have to see when exactly to place your vote. So timing is everything. I hope that answers your question!
