CK doesn't include closed accts for aaoa so it's possibly way off.  How old are your current accts?  Do you have any old/closed accts reporting?  Also, with a 595' i'm assuming you have some baddies on your report.  Getting rid of those will help your score much, much more than another couple secured cards.  Adding a couple more secured cards *could* be helpful at some point, but right now you should focus on those baddies, imho.

Loan 7 months

car 4 months

car 6 months

I do have some other closed accounts reporting a couple of good and about 4 bad

 not sure what you mean by baddies, I did have 4 collection accounts that have been paid. I'm working on goodwill but haven't had any luck yet

'Baddies' are anything negative, like your paid collections.  Since they're already paid, gw'ing them is pretty much your only recourse.  Do you have anything else?  Unpaid collections, charge offs, lates?

it does look like you likely do have a very short aaoa.  Actually, imo, it seems that its so short that i dont think it would hurt for it to get a little shorter by adding a couple more secured cards.  It might help a little to wait until your car is 6 months old, but perhaps not any noticeable amount.  When you do apply for the secured cards check out the cc board to see what your best deal would be and app for them both on  the same day.
