Any advice on jumping into the 170+ range?

LG is definitely my weakness. Currently, I'm scoring at about 75% correct in the section (-6) and if I can get it to -0 to -1 I'd be at around a 170-172. I've been doing tons of the 7sage method in the last month and it has helped a ton, but I feel like I need a stronger final push before December. Any suggestions?
