Mine started at 300, I called after 2 months and got 300 more(before the auto-CLI), then when after the 3rd payment hit, the auto CLI was 500. As on my other capital one card, I waited for the auto CLI and it only gave me 200. Then I called the backdoor number and they gave me 500 more in January on that card. So doing it the way you did, you'll end up with 100 more than if you had waited. Or at least that was my experience.
