Covid Tracker: contact size drops?

Earlier I showed my results for the Covid Tracker (which allows you to log on your phone the hash-key of others who are nearby in case they become infected).

I had some discussion with people about what the ~400 meant. Was that 400 keys I was near? Was it 400/14 for the duration? Interestingly, it then dropped, and is now quite variable.

Have you looked at yours? If you haven’t installed yet, get on it! . Why wouldn’t you track yourself? Its not sharing your data, its letting you track yourself.
