I am a 34 mph skier, my PB is running 22 off, I don't get to ski much but with each set I am able to get in, I focus on 1 detail, not so much focusing on always running the pass as getting that 1 detail down, sometimes it takes a 2 or 3 sets to get that, generally when I get it I will also run the pass, I tend to be very critical of myself, but without lots of ski time it's tough to get good. My goal is to get good, consistent and have all the technicalities worked out before going shorter. I kind of go by the same theory as people in my same work profession, you get good then you get fast (or short if you will). As @Swini says "ski more"!!
