Just curious, what’s the use case for stitching two videos together using the max lens mod that has a 177 degree field of view?

I mount my cameras right on the rink boards as that’s the only place not behind netting, this means there is action directly below the camera and the horizontal POV is too narrow with the regular lens. I incorrectly assumed the Max Lens Mod would give me better coverage as it claims 170+ degrees, but it doesn’t, the max lens mod only works effectively in the hyper view modes which cannot be undistorted in Action Stitch as it’s not fisheye/linear. Long story short the Max Lens mods have been returned
