Thank you for your interest, I've now stayed up until 5:20 am making more detailed logs in a spreadsheet. Heading rows: Mask count, Centre GPS coordinates, Radius (km), Start date and time, End date and time, Comments https://docs.google.com/spreadsheets/d/1ap2lpLXWzK1WcdsasP8cEGn7Bhqig3OlPH9njqh4KYs/edit?usp=sharing https://docs.google.com/spreadsheets/d/1ap2lpLXWzK1WcdsasP8c... Apologies if there's less data tomorrow, I'm not sure what time I'll wake up. But I really wish I could get to Sylvia Park and some other malls and gather some more data points.
