Just eyeballing, it looks like in the three years up to July 31, 2020, Whales fell by more than half in terms of percentage of the whole of users, Orcas almost doubled, Dolphins were just a couple of points away from tripling, Minnows more than quadrupled, and Red Fish did a 25x.
Going in the right direction, and looking good!
Good to see you picking this up again. Always liked seeing it!
