IMO you can't read anything into either the Oct. 31 date or anything else related to TL results.  If company management was that childish to pick Oct. 31 because of the potential of negative results then I would dump everything immediately.  However, I'm not dumping because these folks are professionals, whether medical or otherwise.  You don't get to this stage and this amount of money involved if that were not the case.  So, Oct. 31 is just a coincidence and the timing works for them for whatever reason they deem appropriate.  I wish I could be there and I would definitely attend but I'll be in California attending my daughter's wedding.  As long as TL is ok then that's the main thing.  The rest will come.
