Concgrats on timing it right and your Chase approval, as well as the others.
Though I caution you to stop here and let them age. Chase has been known to AA after the fact, and may watch your CR the next few months for any new accounts.
I too apped the CSP a couple years ago while Amex was slow to report two accounts, which would have put me over. Luckily I restrained from further apps and saw no AA.
