Stuck at 690. Need Advice on Retake!

I'm kind of skeptical to ask for help, but I want to think positive and don’t want to leave any stone unturned. From my past experience of studying for the GMAT for the last 2-3 years is that it's hard to ask help from others since excelling on this exam requires a lot of self-evaluation, which can be hard, and one strategy doesn't fit all.

Anyway, I've attached a PDF that compares the ESR for my last 2 attempts: 690 (Q48, V37) on Mar, 2019 and 690 (Q47, V38) on Oct, 2019, which I both accepted. Not sure ESR helps much since it just very limited data, not reflecting the true abilities of a test taker.

I'm hoping that some experts can guide me on the steps for boosting my score to 730+.

Background about my prep

I've done full Manhattan Prep in-person course and e-GMAT Verbal Live. I've also gone through all Manhattan Prep guides including Advanced Quant and GC Math Book several times. I've done all (i.e. hundreds) the Qs from official sources (GMATPrep, Official, Paper Tests) found on GC. Since my second last attempt in Mar, I thoroughly went through several articles written by Karishma, found in the Ultimate GMAT Quantitative Megathread. I've done Manhattan Prep tests and GMATPrep a few times. I tried 4-5 GC Quant tests, but I didn't seem to like them since I felt that they were just too hard compared to the official questions.

Anyway, I'm extremely thankful to bb, VeritasKarishma, experts and others who are helping in growing this community

Verbal: I believe if I can finish the section for Verbal without having to guess 5-6 Qs at the end, which I always have to, I can cross the 90th percentile. I've always struggled with my pacing. I do have my benchmarks set for every 6 Qs in around 11 min but I always do fall behind due to some Qs.

Quant: I haven't been able to score more than Q48 on the real exam. I've scored Q48 once before. I can easily do the medium level questions with high accuracy, but I only have an accuracy of around 50% for hard questions on GC, even lower accuracy for the ones with 95% difficulty since they are fairly unique and hard to find a pattern to do them.

Prep between the last 2 attempts of 690

I spent 65% of my time on Quant since my percentile for it is quite low as compared to my Verbal percentile. My goal for Verbal was to at least maintain my score if not improve. Unfortunately, my results didn't change much even though I've worked really hard on it. I can usually study 2-3 hours on week days and 4-7 hours on weekend days.

I would do Quant for 2 days followed by Verbal on the third day and then repeat this cycle. Didn't do any practice tests since my scores are going to be skewed. On Quant days, I would usually do 5 PS and 5 DS Qs one-by-one everyday with a ratio of 1:1 for medium to hard questions. For verbal day, I would do 6 CR and 6 SC Qs one-by-one with a ratio of 1:1:1 for easy:medium:hard questions. I would do reading for 20 min everyday and practice 1 RC every 3 days.

My Own Analysis of my ESR

Verbal
• Timing Management for each section isn't helpful since I had to guess last 7 Qs including 1 RC in my last attempt and 4 Qs in the second last attempt so time averages won't be very reflective.
• Took long on SC: 1:51/Q. May need to review material.

Quant
• Areas of improvement:
○ Need to work on PS (49th) since DS was 83rd
○ COUNTING/SETS/SERIES (50%)
○ EQUAL./INEQUAL./ALG. (60%)

Plan for next 1 month

Planning to take my next exam in the first week of December before I head out for family vacation for 3 weeks. Don't have any deadlines since I'm not applying this year, but I feel I shouldn't delay it as I could lose my practice and skills during my break.

• I don't think I need to study more material. Just need to do more questions to apply the concepts.
• Alternate Quant and verbal every day
• Weekdays: Do smaller self-made mock tests, using official questions (i.e. Selected 10-20Q under timed conditions). It takes me quite sometime to review so if I do more Qs, then I won't be able to review them on the same and will have to do it next day.
• Weekends: Full mock test using official questions (i.e. For verbal, selected 36 Q in 65 min: 14 RC, 12 SC, 10 CR)
• Review Error Log every once or twice a week
• Do 1-2 practice tests on weekends: Veritas Prep (have never done it) and GMAT Prep (repeat).

Question: How do I balance my time for Quant and Verbal: 1:1? Any suggestions on my plan above?

I would really appreciate your feedback and help.
