In the last chapter of her PhD thesis Lotte Bransen looked at penalty kicks. Several interesting things emerged.

A simulation study indicated slightly higher save percentage if the goalkeeper did not always align directly in the center of the goal.

🥾⚽️ As noted by, e.g., @zonal-marking.bsky.social a strange trend of the 2026 World Cup is teams deliberately booting the ball out of play from kick-off. With the @royalbelgianfa.bsky.social we looked into this in 2024 for the @statsbomb.com conference.

We can use xG to compute post-hoc win-draw-loss probabilities.

Our new blogpost shows MCMC's estimates of these probabilities are unstable, computing them exactly is faster than approximating them, and MCMC's runtime strongly depends on its implementation.
