I'm having a little trouble with the numbers.
First of all, what's your credit limit on the card? It sounds like you're talking about the balances that might report on your card, not the credit limits.
Scores are strongly driven by utilization of credit ("util"), which is the amount of the balance reported, divided by the total credit limit. So $200 balance on a $2000 CL card is 10% util, $500 on a $2000 card is 25% util, and so forth.
