Actually members are not explicitly assigned to pool accounts any more (although that used to be the case). Now we dynamically select the best account for each upvote right when the upvote is delivered.
You are welcome to edit your submission and I will review again (or you can resubmit if your edit is substantial.)
Edit: Accurate. Response accepted as a qualifying submission.
Don't forgot you can also earn points by scoring the clarity and helpfulness of other qualifying responses.
Wow I was wrong on this one thanks for the update I have changed the answer.
It's one of the things that changed with our automated release. It even changed from our initial announcement, when we still wanted to have semi-static pool assignments. Over time we came to realize that this was a much more elegant solution code-wise and when we eventually fit our accounts to our SP curve goal it will result in a similar outcome (semi-static pool assignments).
I'm happy to talk about how that outcome will eventually happen if you're interested, but it gets pretty technical.
