agreed but what was it before? my assumption since wayback machine didn't capture it is that the baseline was 18 mo like flu/rsv but dunno for sure.🤔

That’s pretty standard statistical methodology… how far things deviate from a baseline determines statistical significance, right? And the baseline is calculated at 10th percentile, not 100th percentile of the previous years’s data, so it’s not zeroing out last year

yes, that's my impression too. they'd need a recent baseline to do the calculation they're doing now, so i doubt it's zero. did they shorten the baseline period for covid because it's not seasonal like flu/rsv? flu/rsv is 18 months, maybe a short period for covid is a good thing bc mult waves/yr?🤔

thank you!
