That's a convenient belief given your position, but I'm not sure how you line it up with the evidence.
How do you align the statement of "take it on the chin, take it all at once and allow it to move through the population" with the subsequent actions? Are we taking it all at once and allowing it to move through the population, or are we taking measures to slow the spread as much as possible? They aren't progressions along a scale, they're opposing goals.
i don't think anyone is suggesting that it was a progression. they clearly changed tact completely once they added in the newer data from Italy. clearly their initial modelling was incorrect, which lead to their original herd tactic.
