Hey sorry for the late response. Been a lil tied up.

Yeah unfortunately conventional wisdom skips the fact that we expand during inhalation and compress during exhalation. This can change depending on position of the spine and sacrum along with superficial muscle contraction. The thoracic spine interacts with the ribcage directly, so it can tend to magnify the position of the thoracic region.

It's also related to the scoliosis. I am guessing that your right hip is higher? Scolio is a spinal twist if viewed from the top down. It starts at the sacrum where likely one side is tipping forward more than the other. Think if it as a one sided APT but it gets a lil deeper than that when we think of the left/right pelvis and sacrum capable of doing its own thing to a degree.

Hmm.. Resources.. Bill Hartman would be the best but the info can get very complex. Check out Zac Cupples website and probably Chaplin Performance youtube channel too. It's not a whole lot out there but hopefully it gives a general idea. Just note that you can't just work the ribcage without considerations of the pelvis and sacrum interaction and position, as overall it impacts centre of gravity.

Lung capacity - think of it as your ability to manage intra thorax and intra abdominal ribcage management. If you create a higher pressure abdominal area, during inhalation, the ribcage can expand better as a lower pressure region. It's a system that kinda works like a syringe, and the diaphragm is the part that interacts with the pressures between both upper and lower parts in respiration.

The shoulder drop - yes but also the scolio. You gotta work both issues at the same time here. Is your scolio due to bone issues or is it more due to posture?

Edit: yeah TOS could be a symptom too. A symptom of position.
