Improving a high Verbal score (V44 to V 46+)

Short version:
I have been scoring very high on verbal (V44), so I spent the last few months doing quant only. I am wondering if its worth it to put in the time to improve verbal, or if my time is better spent still focusing on Quant. First practice tests I got Q39 to Q41, yesterday got Q48 on official GMAT PREP test, but this quant score is suspect.

Long version:
I began studying off and on in March 2015, scoring in the 650 range. I was studying quant and verbal. I really studied hard starting in October 2015, focusing 85% on quant. I took a real GMAT in Dec 2015 and scored 710 (Q43 V44). I had trouble with time on the quant, but had 4:00 extra for verbal. After asking around, I have been told that it is important to try and get close to 80% quant to get into some of my target schools.

I took some time off, then began studying again in May 2015. This time I focused exclusively on quant. At the end May of I took a GMAT Club CAT (quant section only) and scored Q41. Two weeks later I took a GMAT Prep full test and scored 750 (Q48 V44), again I felt rushed on quant but had about 3:00 to spare on verbal. I missed 6 on the verbal, 4 SC, 1CR, 1 paragraph. Traditionally, I have always been better at verbal. In high school I scored 800V 700M on the SAT.

I believe that Q48 score on the last practice test is pretty lucky. I had seen about 1/2 of the questions before because I took my first GMAT Prep test 3 weeks earlier, but didn't get a score (or see any right answers) because I skipped the verbal. Nevertheless, I had seen many of the questions. Next time around that score could easily go back to Q41. Not to brag, but I believe I could score a V43 in my sleep. So, is it worth it to spend any time at all studying verbal? The improvement from V44 to V45 (98% to 99%) might not be worth it. However, I have probably put in about 200+ hours over the last year studying quant, and the recent Q48 score not withstanding, I consistently score 40-43. I take the official test in a month. Will another 4 weeks be sufficient to secure a Q47+, or am I doomed to underperform in quant?

Thanks folks!
