Ah: good news (well, not “good” exactly):
NERVTAG have released this paper on B117 severity which provides some detail. Seems to be a summary of a number of other papers which presumably have more granular data.
Here’s hoping they will be released toohttps://t.co/Xqq3QtGPDV pic.twitter.com/jLzoCOi3qK
