Interestingly Zoe is down today
I don't think that's that surprising, the positive tests in boys3 figures above show that the increase cases was from increased LFD's in school age groups - so almost certainly not cases that would've been picked up before, so Zoe would've already had those.
Does imply that the later festivals weren't that high, which presumably reflects very high previous infection in those groups.
The anecdotes about large numbers in specific schools is presumably schools that hadn't had any real breakout before.
