Of course. I am basing my numbers on facts and science. You are pulling numbers out of your butt.
The assumption that the numbers are spread evenly throughout Edmonton is irrelevant. The assumption that the numbers are spread evenly throughout the population attending the rally is accurate.
Do you have any science to refute that the infection rate among the population of the city was the same as among the attendees of the rally?
Where are you getting your numbers for the number of people isolating in the City? Or non-isolating? It makes zero sense that not one person in the city is isolating. But that's the only way your proportion works.
There is no basis to claim there is the possibility of no infections from the rally. It feels like you are setting the course when the numbers role in this time next week to make an excuse and claim an spike in infections at that point will not be related to the rally.
I like how you think it's so scientific to just multiply numbers by %'s.
It's clear you really don't understand what I'm saying here. You are saying that I can't even entertain the possibility that 0 people were at the rally able to spread COVID-19 because a non-zero % of people in the city could have an undetected infection. I just can't agree with you. There are all kinds of ways that that could be true. If you have a population of 1 million people, and say 300 have an undetected infection, and you grab 15,000 people from the 1 million. There are all kinds of ways that you could end up with 15,000 people without having picked 1 from that 300 pool (picked 15,000 from the 999,700 uninfected). Going by pure %'s, yes, 0.03% of 15,000 is 4.5, so if everything was equal, you would end up with 4 or 5 people, but considering all the factors of what parts of town these young people came from, what the infection rates were in their personal circles. How many of those protesters were very careful up until this movement caught their imagination, it's still possible that the conditions surrounding all the people attending lead to there being 0.
If I had to guess, I'd actually bet people that would take the time to go to a BLM rally may actually be some of the more careful and conscientious people in our population. People more likely to buy into the "we are in this together" mentality, which subsequently seemed to lead many of them to get tested to make sure they aren't going to end up spreading the virus if they caught it at the rally. Obviously it's a little careless in general to go to such a rally, but I understand for many of the people involved, they believe they need to promote change for the long lives many of us still have to live beyond when COVID-19 is over.
