It's as YMMV thing. By biggest increase was hitting the CLI button after my third statement cut. I was given a 1k increase. When the credit steps kicked in I was given 500. It all just depends, I repeated the cycle, charge it up and PIF. Some has gotten higher and some has only got what was in their approval letter letting you know you is enrolled in credit steps.
I received 3K bump on my 2 1/2 yr old Sony Visa to 5.65K recently(Very surprised), Most auto love I ever got from Cap1.
