NOTE: above are the 1-day moves; I checked 5-day moves and the ranges are actually LOWER, meaning that any extreme one-day moves were faded to be less severe after a few days.

With stock at 57.00 the data suggests these ranges:
Based on current IV (expected move into next Friday per TOS): 53.98 to 60.02
Based on AVERAGE move over last 12 quarters: 54.19 to 59.81
