My take on the infected statistics is that its clear people catch Covid at the airport and plane. Most likely the plane, so the incubation period is a few days before it shows up in PCR.
Day 1 is the same day as you step off the plane, so its basically just when you caught the virus
Day 2 is your actually first whole day and if you caught Covid the virus would just be taking hold in the body, with very little time so far to replicate
Day 3 is when the first PCR test currently is done and if you caught Covid in the airport that might show at this point. If you caught it on the plane its less likely
Day 4: You would probably feel some symptoms if you are not one of the asymptomatic
Day 5: Second PCR test and this is where most people get caught, so basically 4 full days after being exposed to the virus.
So how HK government is going to implement anything else than 5+2 I don't really know, since you would not catch people who are infected before they are let out otherwise. Imho 5+2 is the absolute shortest you can implement if you really want to catch cases before they can travel from hotel to home etc. Anything shorter than that and you can just scrap the whole quarantine thingy, which of course would make most sense..
