Since I started to apply mean time between fouls and mean time between stoppages to World Cup data, I was curious to find out if there was any correlation between these “mean-time-between” metrics and the effective match time.  I’ll examine the correlation issues in this post.For reference, here is my post on MTBF for the […]
