> At least 10% of cases

That is likely 10% of people showing symptoms.

The study says 50% of people are asymptomatic (mostly 60+ years old from that data) then the total number of people in population needing a bed halves to 5%.

However I found it unclear from paper whether 50% are not showing symptoms because they only just got infected (i.e. would show symptoms 5 days later on average).
