I judge king Alfonso harshly because he switches me to enemy faster than the speed of light. The real bottleneck of this level is the monk collecting the relic who would return at around 6:00. The point is, you can't predict the exact time. He can be very early, or very late, or not even bother to go out at all. You want him to be late as much as possible to max out El Cid damage to the TC.
