You're welcome. So when we're talking about the backswing for a golfer, what that actually is is a representation of early propulsion. Early propulsion is external rotation, counter-neutation, but it's the sacrum moving back relative to the ilium. So what's creating this? It's actually a delay strategy. So if we talked about the left hip in the backswing, this side is actually going ahead of the right hip. So to create the delay on the backside hip, if we're talking about a right-handed golfer, we're talking about the right hip. So under this circumstance, to create the delay there, what I'm actually doing is creating a yielding action via the connective tissues. So I'm already in an ER representation, but to create the delay, so this side has to go slower than this side, otherwise there would be no turn. So to create a turn, both sides are in ER. One side is overcoming, which creates the turn away from this side. So on the left side, I have an overcoming action of those connective tissues, which moves that hip forward. This hip creates a delay and it moves back. That's what creates a turn. So as I take the club back, and again, I'm talking about right-handed golfers, and I take the club back, this side actually has to slow down relative to this side. So connective tissues behave based on rate of loading, okay? And so the position is ER. Then I create the delay and that creates the space for which I can turn into. Then that's where we superimpose the IR on top of it. If I don't have an ER space, if I don't create this delay strategy on this side, I can still orient the whole pelvis as a whole, but I'm using a compensatory strategy to do so because I don't have the relative motions available. So what I have to do then, Jason, is I have to create relative motions somewhere else. Sometimes I can just create it right there at the hip joint, but this is where you're going to start to see the foot change in the ground because the foot has an early propulsive representation. The pelvis has an early propulsive representation, that match. So if I don't have my true early representation where I have a yielding action here, on the backside of the pelvis, I don't have that representation in the foot anymore. So the foot's going to move as a single unit. The pelvis is going to move as a single unit. And so that's where you start to see people roll to the outside edge of their foot, right? Now I have to create internal rotation somewhere else. And I'm going to usually do that by an orientation where I'm going to tip the pelvis forward. But again, this just creates a cascade of compensations where instead of having relative motions to allow me to capture these positions, I'm using absolute orientations where I'm blocking multi-segmented areas into a single segment of motion. And now I actually reduce my ability to create turn. It's like I can orient myself so I can make myself right facing. But I'm not creating the segmental relative motions that I would use for a controlled segmental movement, which is what is desired when we're talking about these activities so I can acquire effective positions that allow performance to be consistent. Because what happens is, under the circumstances where I'm locking things into one piece, I get way too much signal, not enough noise. And so I can't make the small adjustments that I would normally make to smooth out movement. And so when you get like a golfer or a baseball pitcher that doesn't have these these little segmental movements, what you see is inconsistency with ball contact if I'm a golfer or inconsistencies with the release point of the baseball if I'm a baseball player. Okay? Because these little adjustments here, these little relative motions that I do have available to me is what makes sure that I am consistent because I can make these small adjustments and it doesn't, it doesn't require any thought. It's just the connective tissue behavior, allowing me to capture these consistencies. Okay? Does that make sense?
