In reply to couldxbe:
It's very natural to plateau, or for your rate of progress to significantly slow down at this level. Keeping up the initial rate of progress isn't realistically going to happen - if it did, those of us who have been climbing for 10 or 20 years would be climbing V20 or something!
V3/4 is hard climbing! The kind of moves you get on really hard routes. First of all I'd accept the slowdown in progress, but keep working hard so it's not an actual plateau. There will still be some gains to be had from technique and I think volume is the way to achieve this, plus maybe some drills like 'silent feet' while you're warming up. Really though, I think technique is just a result of experience. So doing a huge volume of every type of problem will improve your technique, which combined with working hard, steep problems for strength will see you continuing to improve but more slowly than when you went from climbing like a beginner to climbing V3/4, which is the steepest bit of the curve.
A fingerboard will help you improve faster, but can be a bit of a shortcut at the expense of technique, turning you into a 7c crimper who can't climb a 6b arete, not a desirable way to be IMO. If you're really serious about getting better, do a huge volume of climbing *and* train on a fingerboard. That's one way that people get really good. The other, unfortunately, is physiological good luck and talent.
