mono-wire, questions about damage from mono-wire Options

[kenny26]

hi there, this is my 1st post on these forums. :)

i wanted 2 make this post about mono-wire 'cause i've looked at the damage values given in the SR3 book, and i'm confused...

it says that if u run into a string of monowire (even if it's placed in neck-height and u're sprinting) u only take 11(S) (or was it 13?) in damage.
i don't understand this, 'cause there's no way of staging up the damage.
pictures this:
Mr. No-name, the combat mage is being chased by a group of lonestart cops and he's running all his legs can bare.
and unknown 2 him, someone's conviniently placed a string of mono-wire across the ally.
he runs into the mono-wire at top-speed, getting cut right in the neck, and he goes on, only taking servere damage!

this makes no sense 2 me... can anyone plz help me out?
have i missed some critical detail in the rules or do i need 2 make a house rule 4 this?

thanx in advance. :)

note: sry 4 the wierd spellings, hope u can chew through it anyways...
