soooo I'm looking at the SAGE paper which suggested the "circuit breaker" lockdown and they've modelled which interventions are likely to drive down transmission, and it seems to suggest closing schools and offices would have a bigger impact on than pubs and household mixing bans

Here's their summaries for each; note how the schools and offices numbers are much bigger than households and pubs.

There's also a very, VERY strong case to be made for closing universities - driving R down, and a strong model (which is what "high confidence" means)
