Loom Geometry

Next question on my new (to me) Macomber!

I noticed last night that the path from the back beam to the front beam is several inches above where the heddle eyes are. This seems… wrong? Or at least counter to all previous jack looms I’ve worked on. Photos to illustrate.

Am I missing something? Or are my heddle frames hanging too low? or is something off in the way the beams are attached to the frame that’s throwing the geometry off?

I could imagine that this is as-designed and meant to give a more countermarch style shed, in which the top and bottom of the shed are equally deflected from the horizontal line, keeping more even tension on the warp threads than on other jack looms, which might be clever, but the photos I’m seeing of other folks with warped Macombers seem to show a level shed, not one that deflects down through the heddles.
