Hello. I am a beginner at 15 puzzle, I started 2 days ago. I average around 40-50 seconds and about 140-160 moves but I can see that most pros average around 60 to 70. I use LBL and I am trying to learn Fringe. I figured that if I can get my move count down, that my times will decrease exponentially, but I don't know how to go about doing so. Any help would be great! Thanks!
