As you know from our many emails and telephone calls to industry participants over the years, many of them have a "When/if in doubt, don't give it out" attitude when it comes to what might be deemed to be proprietary information. That is a natural and understandable attitude to take, especially when the company's representative is ill informed about the matter in question. I just accept it and move on. As you know, in many cases the answers eventually show up in print somewhere or in a video or elsewhere on the Internet.
I agree with scott123 on the W issue since there is nothing particularly secretive about what that number means and now it is used. Knowing that number can be a big help to end users contemplating use of the new GM flour. Maybe over time GM will see the merit of revealing the applicable W number since it is part and parcel of the 00 flours that the new GM flour will be competing with. In my experience, it is the biggest companies that are prone to being overly secretive. I think the reason is that employees of such companies don't want to get into trouble. So they button up their lips.
