In 2020 the week after BF sold 1,256,788 units. So having the minimum poll option as <1.3m might be a bit high as I think that's very very likely.
Going to stop making predictions based on the random amount of stock I think might or might not be available and instead a slight decline from 2020 numbers.
I'd predict about 1.2m dead.
