15 is a lot of inquiries, doesn't matter how old they are.

I've seen a 10-15 point difference with 3/7 of my cards reporting some type of balance. I tend to keep only Ollo and Cap One with balance since they like usage for CLIs. But I'll pay a bit more off this next go around.
@Anonymous The reason for my 15 inquiries arent due to app sprees. 4 of them were from my vehicle purchased when I had to surrender my other truck during the BK. Another one was to refinance that crazy loan. Two were from getting an apartment, which I was denied on one of them. There were seven for my current cards, all spread about the last year and a half. And the last was an accidental one from that Klarna crap that I thought was a prequal, but turned out to be a hard pull. And I'm not obsessed over discover. I've read that it's a good card to have that will grow with you. And I've seen others on here that have just as many if not more inquiries than me and have way more cards and such in shorter time after BK.
@ALLgoodABQ Where are you getting your scores from when you try that method? The only ones that matter when doing that method are true fico scores. Also, you dont have to justify your inq to anyone unless you feel you want too. When i got my first car loan after BK, I decided to go with a credit union, and I unlocked one report (the one they would pull). I knew that dealerships would run my credit across unmpteen lenders, so I wanted to limit that as much as possible, and save my inq for all my cards, lol. I get hit with 3 inquires for an appartment as well, so I feel your pain on that. Also, you're right....there are tons of folks who have way more inquires than you. Some of us would call you an "ametaeur", LOL.. 
Just keep plugging along, doing what you're doing. I feel quite sure you'll get discover
