Did some minor cleanup at the end of 4A -> 4R, and discovered correcting 7A vertical cleaned up nearly all the loss on 7R10 IDX without trading it into another region. Afterwards we were able to send 60 uA to C with significantly less loss present on 7R10 and 9R10. A little more correction was needed from AR -> 5C, nothing out of the ordinary (linked).
Fig 1 is all the IDXs during the tuning period. Fig 2 shows the specific change that improved 7R10, plus 7A y positions. Fig 3 is a roughly apples-to-apples comparison of the IDXs before orbit touch-up (left) and after (right).
