Whatis, as you yourself write, "the company needs to be delivering those answers to analysts now." (emphasis added)
This may be happening, but we wouldn't know about it. The fact that such analysts haven't put MZEI on their "buy" list as of yet, which seems to be the case (or we'd see much more volume), is because the testing is ongoing. So after the next announcements we'll see if in fact there are more eyes on this process than we're aware of.
