Imperfect,
You have a done a great job with your credit and I think you are the exception rather than what commonly goes on here with app sprees. Your credit score jumped nearly 200 points in a year and a half to 750s, which is the highest tier of credit. I don't know your credit history but I would guess you pay in full and keep your utilization low. The fact that you keep getting upgraded shows that lenders find you to be a low risk. I don't even get upgrades unless I ask, and my credit score is over 800 (I do opt out of mailers and pre-screens though).
But I see from reading lots of posts here and elsewhere that people that go on these sprees very often have credit scores in the low 600s. They also get cards with credit limits of $1000 - $2000, which is not very good. A lot of these people don't pay in full and transfer balances, both of which often end up causing debt repayment issues.
I went to several banks in the past few months to learn about car and mortgage loans and showed my and my wife's credit reports for figuring out approximately which tier of loan we qualify for. I have 3 credit cards, 2 of which are 10 years old and 1 card is just over a year old. Average credit line is $10k per card. They said I should qualify for the best rates. My wife on the other hand has 7 credit cards, some are from banks, some from stores, and some from credit unions. Most are 5 years old or more and the newest is 3 years old. Although she has no inquries or baddies on her report and her credit score is around 730, the bankers didn't like having so many cards, especially since the limits were low at $500-2k per card. They said it looked like she applied for lots of cards just to boost her credit lines. This is what the bankers said.
