It seems that currently the only option for playing back a flight is to do it at 4x speed. Having other options would be helpful in order to incorporate playback in presentations.
When you click the play button, it will start playing the flight back automatically at the selected speed (whatever is displayed on the play button). Clicking the play button again will cycle through the available playback speeds. Stop clicking once you reach the desired speed.
Perfect. Thank you for the insight!
