I got the email about my auto-CLI just shy of 180 days ago. Thought I'd give it a shot to see if it would give me the same "there's been a recent CLI. Wait til it's been 6 months" message. Surprisingly, and I mean surprisingly, it offered the $100 increase. 
I obviously am not accepting it. I'm hoping that you'll tell me that my thought process is right. Will they continue to re-evaluate my CLI requests UNTIL I accept it? I want to hold out for something better. I'm willing to continue putting spend on it if it'll increase my chances for a higher limit. When they pull your credit for CLI, are they using the same data that's on your CreditWise report? If not, what do they use?
data points:
-updated my income by just 1k a few days ago
-last begged for a CLI 1 wk ago. maybe i harassed them to death
-last month, one of the reasons for denial of cli was that i wasn't using the card enough---i ditched this card in oct after i got better rewards cards, and then i started using this one again about 2 months ago when i knew a cli was coming up.
Congratulations on your offer!
Maybe if you hold out long enough and put a few more swipes on it, they will increase their offer? 
Pretty sure they are using Equifax Fico 5 (Mortgage) scores from the pile of AAs my CLI attempts have generated.
Usually a myFico thread is started and we wait to see how long it takes before Cap One bashing begins
Which card is it, what was your starting limit, what is your limit now?

If you hardly use the card don't expect anything or much at all that's why they only wanted to give you $100 they are telling you.....YOU DON'T USE OUR CARD ENOUGH! lol
This is my experience with it too, QS1 after a few months a use 1k, then 6 months of meh use 250.
Walmart card 100
QS 100
every time I accept it, because I barely use the card anyway. If they offer it, imma take it

I like Cap1, they let me in when no one else would
