However both reviews were "completed" once two users clicked "Looks OK", this despite the fact that each of them has garnered several deletion recommendations.
I understand that two people having "approved" the post is often a signal that the post is okay; but in both these cases, several others have suggested that the posts are to be deleted (and at least in one case, it's not an answer at all, it's a separate question).
Could it be possible to accommodate this by having a "score" assigned in the review process, and not a "race" between the two type of votes? So if two users vote to delete, it will require four users to approve the post, and if one user has approved the post it will take six users to vote for deletion instead?
Of course this is not without incident, what if a post is being alternately approved and voted for deletion so the score fluctuates between 0 and 1? Well, we add a cut off, and after ten users have reviewed the post without a decision, there is an automatic moderator flag with a link to the review included.
