Credit limit increase on a starter card from Capital One

Not sure why they like me, considering the low spend I put on this card, but they do. You’d think a card that started at $300 was stuck in the low limit bucket. It may yet still be. I still haven’t crossed $5k with it, but it’s not stuck at something ridiculous like the $1500 I seem to be stuck on with Discover. Anyway, my history with this card is as follows: Opened the Quicksilver card in March of 2021 with nothing on my FICO files. Absolutely nothing. This was my very first account. Started at a limit of $300, but i spent around $1000 on the card the first couple months by paying the balance down as I went. It was my only card for a couple weeks until I got the Discover secured card as well. At 3 months they bumped me up to a $400 limit when I requested an increase. 6 months after that, I got an auto increase to $2900 but I was TRYING to get an increase at that point, I was letting the card reach the limit before paying it down in one large payment, rather then paying as I went as I was before, just so Capital One can see the large payments. It worked, even though the card was still reporting with a $0 balance each month. Today I went to the site to update my income, as I just got a raise at work. I figured it’s been another 6 months, so why not ask for another increase? Keep in mind I wasn’t doing anything to get an increase, I only put $500 on that card this month total and the last few previous months have been even less. I only spent $500 this month because I was visiting my mother down south and there are a lot more merchants there that don’t take contactless pay then where I am in NY. This means no Apple Card. I paid it down before the statement cut as usual. I still got an increase to $4400. This card has pretty much been reporting with a $0 balance for a year at this point.
