Okay, we've talked about this before, but it's worth going over again. Some of these things get really confusing, and then we've got layers of competitive strategy to talk about. So if we're going to talk about a wide ISA, so we've got a wide IPA to go with it, we've got a mutation to the sacrum, so we've got an expansion to this posterior lower aspect. So under these circumstances, this would antivert the acetabulum, which would give us plenty of IR. However, because of the expansion posteriorly, we've got a center of gravity issue that's going to knock me backwards. And so my first strategy from our wide ISA is to create that compressive strategy near the base of the syndrome. So I'm going to push the top of the pelvis forward, which is going to take me in that direction. And so now I have a center of gravity issue that's going to push me forward. So I will compress from the front side under those circumstances. So I'll compress the front side of the pelvis. I get a shape change in the SEM which picks up the external rotation concentric orientation and so right away I start to lose my IR capabilities. Now very very late in these compensatory strategies I got to think about post-year lower so when this initiates its concentric orientation very very late where I'm going to bring the sacrum I'm going to bend that sacrum underneath. That will also pick up some of that ER concerted orientation at least initially until we get another shape change in the pelvis. And so late in the compensatory strategy, I'm going to lose some IR under those circumstances. So there's a couple of ways that we can influence this. And it just depends on how far and how deep into these compensatory strategies we actually are. But again, another really good question.
