My opinion would be that its potency coincides with it having more available tissue. Like, I stated above its a slow colonizer, it takes its time "digesting" its substrate with allows the mycelium to dedicate more nutrients to the fruiting body. Its hard to say as to why 1 gram of PE gave you extreme visuals and I would argue I have had similar experiences on PES Blue Hawaiians and Koh Sumai's. Most people are not isolating there Mycelium or Cloning core tissue, they inoculate via the MS(Multi-Spore) which allows a wider range of genetics to come to "fruitition" lol
