no, 91% is just the calculation for a sphere, while the ignis has a cone shaped damage area. but no idea how it's calculated there, could be a increase of the radius of the "ground surface" of the cone (i.e. the point farthest away from the weapon with the biggest spread) which would translate into a 54% increase of covered area (V=1/3*r²*h).
