Have you got the data confirming that this is the case?
This is per https://data.gov.scot/coronavirus-covid-19/detail.html#deaths for the whole of Scotland.
7 days up to 31st May 2021:
COVID cases in the last 7 days - 509.7
COVID deaths in last 7 days - 3
7 days up to 28th May 2020:
COVID cases in the last 7 days - 51.1
COVID deaths in last 7 days - 131
So based on the same time period last year, there were significantly more deaths than this year, yet more cases this year.
I guess my overall point is that this data isn’t the same measuring stick now as it was in the past.
