Take the stance vote before the discussion
Asked at the end, it measures who won the argument. Asked at the start, it shows you the room you are actually in — including the three people who were never going to say so.
Ask the stance question again at the close
Reopen the stance question after the discussion and put the two results next to each other. If nothing moved, the discussion changed nobody's mind and the meeting can be shorter. If it moved, that is the meeting earning its hour.
Read the split, not the average
Six in favour and four against is not broad agreement. In a decision meeting the number that matters is how many people are on the other side, and an average is designed to hide exactly that.
Put the wording on screen before anyone leaves
Type the decision as you intend to write it up, then ask whether that is what was decided. The two minutes it costs are cheaper than the thread that follows a decision nobody can quote.
If nobody can name the decision, end the meeting
The one-word question takes half a minute. A room that cannot say what it is deciding is having a status update, and a status update does not need all nine people or all sixty minutes.
