Good question. I calculated all my wyes that come off my main branch even if the air just goes past rather than through. Not sure if this is correct but I reason that the turbulence of the air going past the wye adds to the static pressure even if the air doesn’t directly go through.

I would agree with that logic but have to think they are not equal. I believe you would only take it on the branch. Take a 6×6x5 wye 5” being the branch. seems to me you would take the 5” wye and add it to the branch. I’m no expert but I have to think on the 6” side the path of least resistance would just get calculated as LF of pipe.
