Still only PCR results in this analysis. I could include RATs but really need to see the RAT situation stabilise first, as most results are still backdated, which is hard to deal with.

With the projected peak of the NSW outbreak approaching, it's worth showing how sensitive my projection is to one of its main assumptions: the fraction of infections that are being captured by testing. 1/6
Current projection is based on the assumption that 20% of infections are being detected. That implies there are a lot of infections contributing to immunity that have not been detected via testing. 2/6
If the detection rate is higher, say, 30%, then there are not as many undetected infections out there, and therefore less immunity. High immunity is required for infections to peak, so that implies the peak is a little further away (and higher, in terms of detected cases) 3/6
