Yes, there is an another account @gsaw, which repeats votes of this top. It checks, how much points collected by the top voted post. At the moment, it is just the count of top curators voted for that post. If more then one voted, or one of 3 from top, then @gsaw repeats the vote. With vote weight x 3. Then sleeps, until vote power restores. There already some accounts follow gsaw's votes. But I think this just disturb the top, because it increases curatition rewards for the top curators, and they will stay top curators, because these are top curators. :)
I am about to add more metrics. I will collect additionaly statistics of top authors and may be tags, in order to make better predictions, which post, will yeld more return.
