I'm new here, but it seems obvious that it follows an order.. . . .
View post, Agree, Positive Comment, Upvote, Resteem... Up Voted. . .
View post, Agree, Positive Comment, Upvote... (Maybe no resteem) ... Up Voted
View post, Agree with No Comment, Upvote, (no resteem) . . . Up Voted
OR
View post, Agree with No Comment, no upvote, no resteem. . . .
OR Even
View post and not much interest gets no vote . . . 0 vote
View post and Disagree, gets no vote . . . . 0 vote
View post and Disagree with Negative comment, no vote . . . 0 vote

BUT... basically if there is a Positive Comment, there should be an Up Vote.
