I’m not a lab scientist, and haven’t worked in a lab since undergrad, but they say the method was end-point titration on Vero E6 cell—i.e. they put the sample on a bunch of cells that come from a standard line (of monkey kidney cells) for it to infect those cells, and tested those cells using titration.
That sounds like licking to me.
Also, +25 points to that paper for using Stan for the markov-chain monte carlo modeling, and only −10 for having appendixes in MS Word format.
Edit: and they do say the results for cardboard were unusually noisy, so it’s less reliable, but either way the virus was dead in a day.
I’m working off this paper, which did test cardboard.
