Attention at a live moment is thin, so scoring had to read instantly. The leaderboard led with top speed, highest score and the most recent player, timestamped to the minute, because a leaderboard that moved minutes ago is social proof and a reason to come back. The court diagram turned a raw speed number into placement and trajectory, so a score read like a real serve rather than an arcade figure. And every path on the page pointed at one action, getting the app, so the live moment kept paying off after people scrolled away.
