Hey Ryan, if you wanna get better at cubing then you gotta get better at the things that you're not better at.
It'd be great to know how you practice, because there are many different ways. You can practice specific areas of your solve, do untimed solves while trying to improve your efficiency, learn new things, or just mindlessly practice your times (which is not a bad thing, but usually not the best).
30+ seconds average is still in that area where speed doesn't matter. During my first method, CFOP, 30+ seconds was as good as my cubing skill was at the time and breaking my own records was a big deal. However, like most experienced cubers will say, just worrying about your times could slow you down compared to if you practiced the right ways.
For me, speed wasn't a big factor in my solves until trying to get sub-15. What I'm trying to say is don't worry about your turning speed during non-algorithm parts of the solve, and look ahead is very important. very.
Like, if you wanna main ZZ, plan your EO-Line and look ahead to your first square or corner-edge pair while you're doing it. Turning fast without good look ahead will save only a little bit of time, while blurring the cube and causing pauses. Practice smooth solving and conscious look ahead and such, until the last layer.
For Roux, plan out your first block (which isn't too hard at first if you're not colour neutral) and look ahead to second block. Lots of look ahead for LSE as well.
For CFOP, look ahead to your first pair during the cross, and obviously keep looking ahead.
Just speaking from experience, usually my PBs have very smooth or short F2L/blocks, and stuff like PLL skips or LSE skips alone make less of a difference.
You don't have to main any method yet, each one will help you in another one. I remember Feliks said he averages like 12 with ZZ and 15 with Roux, so clearly knowing a lot of methods won't hurt.
tl;dr
- prepare yourself for when you're fast, by practicing the things you'll be doing when you're fast. the right algs, look ahead, optimal cross, etc.
- in a few months or a year, your current PBs won't seem so omgawesome. worry about being a faster cuber, not just having a faster PB.
- do untimed solves, do smooth solves to a metronome, figure out shortcuts while doing slow solves, etc. try going off your regular practice pattern.
