Welp, this may not be the best answer but maybe you could try getting better at stuff like the cross or F2L lookahead if you haven't done so already. You could also try recognizing OLL/PLL patterns a little bit faster, again, if you haven't already done so. Look up a few tutorials for the cross & F2L (Don't really have any specifics in mind..) For the OLL/PLL, you could try drilling or use a software trainer. ^^
Now for my question.
Would it be a good idea to take new things I've learned (lookahead, color neutrality, etc.) and while doing solves, slow down to implement what I've learned instead of going fast as usual? Then gradually go a bit faster with the solves?
