Port Calculator Question

[kfx450r 10+ year member]

If I use 4 ports for example and it says the length is 30" ...does that mean each of the four ports (round) is 30" or would each be 7.5"

I notice one 8" port the length was like 31" and 4x 4" ports (same area) is 33" so it just seems like the port length would be divided amongst the smaller ports.

If you have 4 ports and they say 30" on the calc, that means you need each individual port to be that long. So in total you would need 120" in whatever size port.
