Again, all I'm trying to do is make different instances of the same object fire at consistently different rates I could set.
Well I've done it here in 2 events. https://www.dropbox.com/s/uwzrvqdh2tlu9 ... .capx?dl=0
I did it two ways, you can either set the timer wait period to the fire rate, or you can set the speed of the bullet to the fire rate. Both have the same outcome.
If what you want is for all t1 to fire at the same changing fire rate and all t2 to do the same etc, then you can split out the family event into the 4 types of ship.
