Remember that we're talking about pleasing two different entities: FICO and your CCC. You're right, FICO scores will only be affected if your CCC reports a late to the CRA's, and usually the CCC doesn't do that until you've missed the second due date. But you can bet that your CCC is keeping track of your payment history, and if you frequently miss the due date, it's going to figure out that you've got problems, and up goes your rate.
Same thing if you GW a baddie off your credit report: the CCC might be willing to stop reporting it to the CRA's, but it knows that it happened, and the baddie will be factored in when you ask for lower rates, higher CL, or an additional card.
Since your other CCC's periodically soft your report, they will see if you have lates. I think that they also see your payment history and APR's, although maybe that's just on hards. Someone once posted that lenders get reports that are WAY more detailed than what we can see as consumers.
