Thank you very much for the correction. I don't know if I misremembered a peak rate at some particular time (perhaps when America was still a colony and lacking access to great medical care facilities) or mere statistical trickery like also including stillborn deaths (at which point it might be even higher, bc the rate of auto-abortion by the fetus itself in the very early stages of pregnancy when no symptoms are yet showing I thought was unknown, though later on when pregnancy becomes detectable it is said to be 30-40%) or what, but I edited my response to avoid spreading misinformation.
