And, in addition to the PR, JB noted on the CC the relationship with the lab has expanded, adding scientists, working on technology for niche markets, etc.
I could be wrong, but I think if shareholders are thinking sometime very soon the lab is going to have completed all its work and there is going to be some single, final "yes P2O works", they might off in their expectations and looking at the 3rd party lab effort a bit one-dimensionally.
I have not spoken to JB about the lab work at all, but my read is that the lab is working with us on several aspects and goals and that this work will be ongoing for awhile.
