Based on my high GPA (3.98), most suggested that I should rewrite because with a 167 (first time writing LSAT), I'm throwing away my GPA.... and I agree

The following is my spread on my October writing
LR1: -7 (first section... I was very distracted by other people's pencil sound...)
LR2: -3 (this is my actual range based on practice test)
LG: 0 (never got -0 in PT -- my practice ranged from -1~-4)
RC: -5 (underperformed -- my practice ranged from -1~-3)
What makes me more upset is that I actually switched from right to wrong on two of the questions

My PT range (most common scores, barring on outliers)
LR1: -3
LR2: -3
LG: -1~-4
RC: -1~-3
My PT total range was 165~175, 165 and 175 both being outliers. My mode and average was both 171.
I was very stagnant throughout my prep, ranging from 169-171. Frankly, I wasn't very ready for my LR sections as I didn't focus much effort on them, and clearly, I paid my price.
For the record, I studied for 3 months last summer but never wrote the test. This year, I prepared for 1.5 months before going into my October test, with very little improvement in my practice score during 1.5 months period (but my average PT was much higher this year than last summer).
Given all of this information, do you think I could increase my score in DEC writing to about 173? (minimum 170...)
