/**
 * Each bot contains a object of hitrates, for each multiplier like
 *   hitrates: { 1: <single_hitrate>, 2: <doubles_hitrate>, 3: <triples_hitrate>, 0: <miss_chance>  }
 *      single_hitrate : Percentage chance of hitting a single
 *      doubles_hitrate: Percentage chance of hitting a double
 *      triples_hitrate: Percentage chance of hitting a triple
 *      miss_chance:     Percentage chance of hitting a Miss when missing a Double
 * 
 * As well as a miss range, which is how far off the given target the bot will miss. 
 *   For example, if the bot is going for 20, and miss range is 3, it could hit 20, 1, 18, 4, 5, 12 or 9
