There are six working days left before they go on their annual holiday shutdown for Hannukah/Christmas/New Years.
It would be irresponsible for them NOT to update us before leaving on their vacation. Expect an update before Dec 15th.
Given that the packer, made out of rubber, is probably installed now, but can only last five or six days due to the high temperatures at that location; that would indicate they most likely will be driven to finish their testing by that date, Dec 15th..
No update at all would by Dec 15th would probably mean very bad news.
A gambling man might buy the stock now, hoping for a good report by Dec 15th, and selling on or about the 16th, if no report is forthcoming.
