I think it would be an informative way to test the assumption.
Well, yes, but too late for that now. In addition, if she hadn't removed those credit lines from being associated with me then they couldn't approve the new card unless I was ready to submit all necessary financials to prove that I can be eligible to hold such a large total credit limit with Chase. So obviously for me it was easier to have them remove all those lines from my profile to bring down the total to an acceptable level and then move credit from an existing open line.
