Rich said: Yes, good question. To some degree I am going to say "hold that thought" because we are going to discuss that during phytochem and you can ask more if I don't go into enough detail. Very brief answer: yes double extractions are good, but I am still not convinced it is the best way in most cases to take the mushrooms. I prefer good old fashioned decoctions, or cooking into broths or soups, or powders that have been heat-treated (steamed or something similar).
