As far as Disco CLIs go, you may need tarot cards, ouija board, tea leaves, voodoo doll made out of shredded credit cards, and probably a goat if you're looking for accurate data.
Some of their unpredictability probably comes from ABS, so future success is somewhat predetermined at the time of approval, but to a lesser extent than Cap One and their ABS model.
Some see decent increases with a lot of use, some with minimal use. Some cannot get a CLI for years, while others will receive several during a calendar year. I'm one of those.
There were times when card was used rather heavily. Since last April, I've used it once (in error), yet ive gotten CLIs totalling $11,500.00 since June.
Probably the best way to go about it is just use your card like you normally would, when it makes sense financially. Ask once a month, but wait a few days after statement is ready.
Most of auto increases happen a few days after the statement, so no need to waste request if you were already supposed to get one.
Other than that, there isn't much else you can do. Some members have reported getting increases at some point while they carried a BT, or after BT was paid off.
