  Some people just have very mild symptoms that they don't recognise. A lot of people don't notice their temperature is raised for a day or so. Some lists of symptoms don't include anosmia or diarrhoea, so people have symptoms but don't think these are covid-19 symptoms.

  Hard to know without widespread testing, and it depends how people define asymptomatic. But cruise ship cases seem to indicate people with no true visible symptoms. There was a cruise ship with universal masking and a 80+% asymptomatic rate after 28 days. Now, these patients may well have symptoms such as ground glass opacities in the lungs. But you can’t exactly feel that, so that’s some of the ambiguity.

  Yes you are wrong, though I suppose what you consider "rare" could be arbitrary. It seems that asymptomatic cases are anywhere from 20-40% of cases, although even that could be low, given that you are more likely to be missed if you have no symptoms prompting you to get tested.
