How hemaglutinin work

Re: How hemaglutinin work

one cell produces 500000-1mio copies of the virus, but the mutation
rate is so high, that only about thousand survive, the others
are nonfunctional.

I read this some time ago, but now I can't find it.
I can't believe now that only 1000 are copied correctly.

Also:
how long does one cell-infection cycle last before the new viruses are ready
to enter other cells ?
how many original H5N1 viruses are usually infecting a human ?
How many enter the human and how many of these succeed in infecting
a cell ?
How many viruses are leaving a human by breathing or coughing
or sneezing per infection in average ?
How many of the viruses produced in one cell succeed to infect another cell
in average ?
I'm interested in approximate numbers for normal flu or H5N1
