"The web materials can be tailored to any coefficient of elasticity desired merely by multiplication of filaments, "
that certainly aint a new concept...
No it is not. It is basic physics and materials science.
It is a response to your previous statement that

a suspension web aint gonna help anything...unless its gonna be one big helmut...

Because it is possible to build such a web with a very high coefficient of elasticity it is not necessary to make a helmet any larger for this approach to work.
..and the material used would make no major difference...
The entire concept is predicated on the extreme Toughness of spider silk. The material used makes All the difference!

"I expect that the average warfighter"

they are called soldiers..
You call them soldiers, the DOD calls them warfighters.

"will gladly tolerate a 20% or more larger helmet diameter if it gives him protection from direct hits by heavy machine gun projectiles. "

they are called bullets...
A bullet is a semi-specific name for one of the many types of projectiles encountered in warfare and by safety helmets in general.
A hot rivet impacting a construction worker's helmet after a 200 foot fall is not a bullet, but very definitely a projectile.
Ditto IED fragments etc.

"The toughness (area under the stress vs. strain curve) will directly scale to the product of diameter and total energy absorption. "

we are talking about a bullet to the head... get real

This is unfortunately a Very Real issue.
Recent helmets are proof against a direct hit from relatively small caliber arms and glancing hits from larger caliber projectiles such as those fired by heavy machine guns (exact numbers are classified).
Direct hits from large caliber arms will penetrate the helmet.
The helmets could be made stronger to resist such direct hits but two factors prevent this.
A) total helmet weight.
B) a direct large caliber impact carries enough energy that even if it did not penetrate the helmet, the impact energy transferred to the helmet and then to the head would be sufficient to kill via concussion.

Better penetration resistance without too much added weight can be achieved by the use of advanced composites such as MS or BR reinforced materials.
To protect against concussion the energy transferred must be spread over a longer time interval as well as a wider area.
The Web support structures envisioned in this patent might be able to accomplish this.
