Great breakdown and analysis Ian.
Have you considered using screen recording software instead of recording the iPad? This will allow you to record audio while the viewer is seeing exactly what's on your laptop screen. You can then use your pointer to highlight things you want to bring viewers attension to. There are many paid and free versions of software available which are apparently easy to use.
