is my outtake fan too far from tent port?

[matt11]

I have my inline fan (outtake) positioned 12” from my tent port opening, via ducting on both sides. Will having the fan this distance from my tent cause loss of CFM’s? It still sucks awesome, and I can’t tell a difference then having it right next to opening.anyone else keep their outtake fan NOT right against their tent/grow room? And due to obstructions it would be a lot of work to move the tent back 10”-12”, to me its not a big deal since its not too fan away, but definitely do t wanna be loosing too much CFM'swhat do you guys think.
It’s a hurricane 435cfm centrifugal inline, with no filter or anything attached or obstructing. Just the fan with ducting going to tent, and ducting going to outside

You shouldn't see too much reduction in cfm's..
I've ran them several feet away before, with minimal reduction
