I'm not sure about any specific numbers. Keep in mind 2 different reasons for doing credit checks:
1. UCMJ requires that military members pay back all just debts. Occasionally, some people get into disciplinary problems for not paying their bills. My experience is that it takes months or years of not paying bills for any UCMJ actions to occur. We had a guy who was evicted out of 2 houses, had cars repossessed, and did a lot of other stuff and it took about 2 years to discharge him. His official discharge wasn't even for the financial stuff, although it could have been.

However, it seems that your case is probably more of an administrative issue and probably not a habitual inability to pay back your bills.

2. Uncle Sam does credit checks as part of the security clearance process. Bankruptcies will affect your ability to hold a security clearance. Basically, if you're perceived to be in a situation in which you could easily be bribed, then you could be a security threat and won't be given a clearance.
