Yes but your taking advantage of the good genetics and pushing them hard as your previous knowledge experience allows. ,,*for people starting off if you replicate say how @mephisto grows you are giving your self the best possible chance of replicating a great indoor harvest
This is the truth, you've got decades of experience, and with only 4 plants going, they're getting daily attention. The fact that you get great results regardless of the breeder doesn't mean somebody else could.
