1% is about expected at that point, since there is a 14 day lag on average and CFR can only go up over time after new cases trail off, it should end up higher. Look how South Korea eventually rose from .7% to 1.8% (somewhat biased by lots of young people infected early, but most of the rise at least from 1% to 1.8% was just due to the lags involved).

Maybe it is still a good number for their population age demographics and the treatment helps a lot, but it doesn't seem to be showing it to be anything like a game changer.
