m/s² — acceleration magnitude below which flight starts

m/s² — acceleration magnitude that signals landing

degrees — minimum beta rotation to count a flip

degrees — minimum alpha rotation to count a 360 shove-it (instead of 180)

ms — minimum flight duration to avoid false positives

ms — how long acceleration must stay above the impact threshold before confirming landing (filters out spin spikes mid-flight)

°/s — minimum floor; rotation mainly needs to drop below 30% of its peak to confirm a real landing (distinguishes "caught in hand" from "still spinning")

°/s — also starts flight if rotation suddenly spikes, even if acceleration never drops low (a very fast spin generates its own centripetal force that can mask free fall)
