Congrats on the high limit. I love my chase cards and look forward to being approved for the CSP in the near future.
As JohnWillyson said, you have no reason to be concerned. You may not even be at the internal limit that they will lend you right now. I was recently approved for 17,000 and the next day for 25,000 without having to ask for reconsideration. So you should have nothing to worry about.
