Expected time until 50% and 75% vaccination?

[LiSongMWO]

Would it be possible to add predictions based on the 7 day average and current deployment of how long until 50% and 75% respectively of the population has been vaccinated?

With the usual caveat that using statistics to extrapolate numbers like this is not an actuall prediction (taking planned availability etc of doses into account)...

Certainly! Would you like to propose a patch?

Note that the calculation would become more complicated one single-dose vaccines become available.

Normally I'd offer up a patch but JS is a language I'm not proficient in and I don't have time to be learning it for this one purpose :/
