Imagine you needed ONE STUD to win a campaign battle that took 2 months and a half to finish. You have just the last minifig, only with his left arm holding the jewel that is the key to win the quest.
You even tried to sprint, but you rolled 1. Unfornately, by another modifier, you lost one inch of Move.
That makes 5 inches, counting as 15 studs. You go and...1 more stud and were in the safety of the ally castle!!!
If you choosed to have it 15 studs, you were killed by one rifleman because you ended up diyng in the front of the ally castle.
