I want to know the answer to the following question:
What was the largest number to use Underground shelters in September  27, 1940?
All the background I'm provided with is that "Peak use of the Underground as shelter was 177,000 on 27 September 1940, and a November 1940 census of London found that about 4% of residents used the Tube and other large shelters; 9% in public surface shelters; and 27% in private home shelters, implying that the remaining 60% of the city likely stayed at home.". Is that enough to answer the question?
