L Shape port and WBIN??

Hello,
I’ve encountered a problem while determing the ports for my cabinet. I’m not sure where exactly I should measure from and how to do it correctly. Does port represent only blue part or with green? Or only green, and blue part as a front chamber?
So far, I’ve been using ChatGPT to calculate and tune the ports for me, but I’ll admit, I’d really appreciate some feedback and opinions from professionals.

I’m attaching a file with my design for reference.

I'd make a different shape depending whether it was better to pass larger or smaller wavelengths.
Yes I agree, I reshape it to look more like OG W-Bin. Thats make more sense.

Iam trying to put parameter to hornresp, and have some calculations done 😅, but I have a question, how do you calculate w-bin horn? U divide by 2 coz it looks like to horns, or calculate only one segment?
