Yes it make sense.
On MULT you set how many bombs you want to launch at time, if you want to launch 8 bombs in total in packs of 4 and with a space of 1000 feets you set:
QTY 8
MULT 4
INT 1000
And you dont launch 32 bombs :smilewink:
I dont remember if you cant launch s6 bombs at time or 4 its the maximum, but you can launch 8 bombas in packs of 4
Edit: i test it and the max bombs you can launch per time are 5, so if you want to launch 6 you must configure:
QTY 6
MULT 5
INT 1
I dont know the logic about this but you clearly misunderstood Chuck´s guide
