I think GE/Honeywell or other big companies will know if Sigma's product will be the standard prior to being the standard. Thus they won't give Sigma a big contract for something they can have for pennies on the dollar.
Sigma has to find ways to raise PPS well in advance, and on their own. It will not come through a big GE contract, that I'm convinced of.
Again, I've asked for help in putting my mind back on track if my logic makes no sense. So far nobody has come to the rescue, making me think others are in deep thought or agree.
