Sherpa, surely you fly into Dover, DE from time to time. Next time let me know and I'll show you how I get 90+ everytime. Matter of fact, when I started brewing, I brewed with recipes set to "mid" level efficiency. My OGs always ended up WAY high. It took me a while to realize/admit that my efficiency is high. I've even tried to tempt fate by sparging quickly (valve open full-bore) and I just can't seem to get under 90.
