Follow the course of a match using heatmaps.
Set 1 – Attacking team able to hit the middle of the court and score at a high %.
Set 2 – The middle of the court is being closed. Attack effectiveness decreases.
Set 3 – Pos 2/1 cannot get the ball past the block. The attack that gets past the block is funnelled to the defence.
Set 4/5 – Nothing gets past the block. Attack % under 40%.
