Making nukes more deadly in civ 4

I posted this in the civilization 4 forums but that forum is dead so i thought i'd try my luck here. I got annoyed that nukes worked on a chance system when in real life they destroy everything, so I opened the XML and set nuke fallout prob to 100, nuke unit damage base to 100, nuke building destruction prob to 100 and nuke population death base to 100, but there are the values nuke unit damage rand 1 and 2 and nuke population death base rand 1 and 2 that i didn't change because i didn't know what they did. Can anyone tell me whether nukes will now kill all units, buildings and population or whether i have to change something else. BTW I tried installing MAD nukes but it didn't work. Thanks in advance.Making nukes more deadly in civ 4
