Don't forget that the lunch break can have an impact on the outcome:
The [research] team found that, at the start of the day, the judges granted around two-thirds of the applications before them. As the hours passed, that number fell sharply (see chart), eventually reaching zero. But clemency returned after each of two daily breaks, during which the judges retired for food. The approval rate shot back up to near its original value, before falling again as the day wore on.
If something as simple as a lunch break can have this type of impact on judges, then imagine how other circumstances of their personal life can impact longer trials.
