My surmise for the reason behind the blip is motor burnout. The airframe might compress a bit under power and drag, then relax at burnout. That transition might cause a tiny, momentary drop in air pressure within the airframe and trick the altimeter into thinking it "backed up" (or "jumped ahead") a few feet before continuing on with the coast to apogee. Just a guess.My FS sometimes (lees than half) gets the hiccup at cut off and the acceleration drops. Obviously the rocket doesn’t drop in elevation or freeze in time, so what’s going on here?

The altimeter gets the weather data from some nefarious source. I’m not sure if at the time of flight, when it’s downloaded to the phone, or when uploaded to the website.
Good skies,
