Another newbie here...after a weekend spent on the couch with laptop, cold medicine, and kleenexes, reading posts until I'm glassy-eyed, I now know enough to be dangerous. The credit reporting agencies only know the figure that your credit card companies report to them. If you're just about maxed out when they report, and then you pay them off after the data goes in, the CRA's don't know of your wonderfulness.
I called my CCC (the truly wonderful USAA, may they be forever blessed) and found the dates when they report to the CRA's. In both cases, it's the dates that the statements drop. So all I have to do is pay my cards down to the magic 1-9% about 5 days before they report, and the CRA's will be dutifully impressed. I hope.
You have to keep in mind the difference between what your CC's know about you (which would influence them in increasing your CL, for instance) and what the CRA's know about you (which influences them in setting your credit score.)
If I'm wrong, someone with experience please come rescue both of us!
