Not so important

what would your total be for the last 2 years combined? Don't know if that's easy to work out on ebird or wherever.
My ebird; World Life List; Last Seen
Last 2, 3 or n years is easy. Harder would be to figure out how many one has seen between 2019 and 2021 for example. Still, with exports and a bit of spreadsheet wigling it ought to be feasible too.
