Editing the grenade fragments

I just want to make the grenades/cannons spew out more fragments  I've been digging through the files but I can't pinpoint the exact bit of code that defines how many are created once the grenade/cannonshot explodes. Anyone know where I can find it to mess around with it?

You can use Warband Battle Resizer to set it to whatever you want
