Black Widow vs Golden Orb...

Entogenetics is using gene sequences from the black widow spider, while KBLB and most others are using sequences from the Golden Orb spider. KBLB's patent rights only cover Golden Orb spider silk, not that of Black Widow spiders. I don't know much about the stretch/strain curves of Black Widow silk.

The video was recent -- November 18, 2016 (had to search for the date). According to Prof. Brigham, they haven't achieved homozygosity in their silkworms yet. I'm guessing he recently used CRISPR/CAS instead of whatever method he was using previously.

If KBLB's experience and that of others proves true, he has a way to go before he has a stable genetic line.

I've not seen data that spider silk is 5 times tougher than Kevlar. Most of the reports I've looked at report a factor of about 3.

The pad he was showing is not a shoot pack. The ones KBLB is making for the Army are 18 inches square. A small pad like the one he showed will test better than larger pads, especially if you are only looking at penetration and not at backface signature depth.

Entogenetics has a big Mulberry tree farm already, but they do not seem to be producing large quantities of spider silk. Nevertheless, KBLB should feel a little more pressure to get out there to market.
