Ideally, the chances of getting a top prize would be either 20% or 16% (out of 5 or 6 possible end rewards, respectively). However, maybe the game's alogrithm or rewards system is tweaked to increase the chances of getting the other LE prizes and, in turn, reducing the likelihood of getting the top prize. So instead of the probabilities being 20-20-20-20-20, the system probably has it at 10-15-15-30-30.
