Bootstrap mode is legacy?

I wasn’t familiar with this, you are right. I made a PR to change this by giving higher default first-day limits for TL1 users and also by starting the clock at the user’s created_at date. Previously we were using the first post date, which is an odd choice, it can mean that a user could have “first-day” limits on their Nth day on the site, if they reply first only on the Nth day.
