Am I on the right track?

I'm probably not playing ideally, but I've been playing for about a month, usually hopping on to do my dailies and then a career run or two. At this point all of my top veteran Umas are B or B+ and I've just started breaking into 9000 for uma ratings.

Am I about where I should be after this amount of time and this play rate while not spending much? Or is there likely something significantly wrong with how I'm playing to not have A's and A+'s at this point?

I don't need specific advice. I'm confident I can figure out what I'm doing wrong, but at the moment, it feels like I just need to grind for more carats.
