I just labeled the photos in-line.

There are two significant flow restrictions on your piping. The first is the 'train-wreck' piping, typical of Jandy valve layouts, which sets up two opposing streams of flow in a collision or 'train-wreck' layout. It's not so bad when the flow come from the 'stem' of the tee, rather than the arms. This is the case on the return piping. But, it's quite bad when the flow is coming from the arms and exiting out the 'stem'.

In fact, it's SO bad I've never been able to find a pressure drop table on such a layout, in either pool or plumbing tech literature. I guess the engineers assumed that anyone with enough sense to use such tables would have enough sense to avoid such a layout.

The second flow issue is the check valves on the loop on the wall. Valves like these sometimes have springs in them, that can result in enormous flow losses.

If the loop serves no purpose, it might be best to remove it.
