How to get over the small hump to 165

Today I scored a 161/162 for the 5th time in 10 PTs, most of my others have been about the same range, 159/160. Today's 161 was the best I've done on a PT across all 4 sections, -6 (RC), -4 (LR), -6 (LR), -6 (LR). To get a 165+, you need to get 14 or less incorrect; Today was -18 (-6 x 3), but was the best cumulative 4 section score I've gotten. I have found myself improving drastically in drilling, following close to target time results, I'll do drills of my weakest type, 4 and 5 star NA/SA/Weakening, and get very, very few wrong. But when it comes time to test, I feel like I find it very hard to get the 5 star Q's right, in drilling I have no problem with them (comparatively). Still, maybe due to the mental fatigue of an entire section, I find myself getting almost every question (~90-95% accuracy 1-4 stars) right up until the 5 stars, and then have my sections fall apart (specifically in LR) from 17-25. What should I do to remedy this? I drill 15 LRs and aim for ~18-20 minutes target time, and 2 passage RCs ~17-19 minutes target time.

What did others do to break out of this pre-165 bump. I take the august in 2 weeks, my hope is that I can put it all together before then and get a 165, if not, my more reasonable test for this achievement is september.

I know of some LSAT demon strategies, that I've read recently, where some people say go for 100% accuracy, guess on the last, this is surely interesting. But I've been trying to do, and do successfully, 10 questions in 10 minutes, and then 15 in 25. I think I'm going to change my strategy to 15 questions in 15 minutes, and then leave 20 for the last 10, as I feel myself needlessly dragging my feet through 11-15.

Any thoughts are appreciated.
