Just go ahead and round it up to 66.6%. There's no reason to be coy anymore.
I've noticed that in the recent string of "tested positive" collaborators also say they are experiencing "mild symptoms" another with the exact same scripted expression. But as I recall, some say that. Some say, they don't have symptoms but are isolating "out of an abundance of caution." etc. etc. Who's got that meme with the list of quotes/tweets? TIA
