True, but a building having the highest return on investment does not mean that building is best to have on your Island. It depends on how frequently you collect income from your buildings. If you play the game hours on end, the buildings with short 100% accumulation times have the highest yield. If you only check the game say twice a day, you are better off having buildings with long 100% accumulation times.
