I am not sure why many of the hunts are going to 3 days. I do know with the good quality outfits what isn't the reason and "If your species that you offer is above par you get to move twice the amount of hunters through the same season and therefore it doubles your income for the same amount of work...in theory" is not the reason. Quality outfits are not after moving twice the number of hunters through and in fact the good ones keep it very limited on the number of hunters they book and the number of mature bucks they allowed to be shot.
