Hey @Dylan Walsh great question! In the pronation EOW, we're looking for as close to "perfect" pronation mechanics as possible, related to walking gait. To maximise the amount of motion, we start from heel strike to get as much pronation range of motion as possible (from a fully supinated foot towards a maximally pronated foot) In David's case, many of his issues related to the squat, so the pronation mechanics can be thought of as partial/mid-range compared to a footstep in walking. We're just looking at how the foot pronates from standing to squatting, so we won't see as much change. One point to clarify is that pronation can and does occur when mass in on top of our centre of balance, the ideal pronation just *starts* when we're behind our centre of balance. Think of it as giving the most space to pronate into. A squat analogy for this would be squatting from standing vs squatting down from the power position. We're still squatting, but if we start standing we have a better change to set up ideal mechanics. Typically maximum pronation occurs when we're in mid-stance or "suspension" phase of gait as Gary Ward would call it, before the swing foot overtakes the stance foot. Let me know if that clarifies things or if you have a follow up question please fire away!
