Something worth noting from your score breakdown: your Quant dropped from Q85 to Q80 between your two attempts while DI went up. Now your practice test shows Q80 still. The advice others have given about DI needing work is accurate for your November scores, but your bigger opportunity might actually be getting Quant back to where it was.
A 5-point quant slip usually isn't a content gap. It's either timing or a few specific concept areas where you're getting questions right by intuition but wrong when the problem is slightly harder. With TTP for one month, I'd use the first two weeks almost entirely on Quant diagnostics. Do timed mixed sets, tag every wrong answer, and look for patterns. Problem Solving on Number Properties and Inequalities are the two areas that most often cause 700+ candidates to drop points without realizing it.
For DI specifically, your Data Sufficiency will improve as your Quant fundamentals tighten. The Two-Part Analysis questions tend to be the bigger time sink. If you're losing time there, work on identifying the constraint structure first (what's fixed, what can vary) before trying to solve. That framing saves a lot of rework.
2 hours on weekdays and 3 on weekends is a solid pace. The thing I'd push back on from most advice is the idea of spreading prep evenly. With 2-3 months, pick one section to go deep on per week. Full rotation takes too long to show results and you lose track of what's moving.
You're not starting from scratch. 615 to 700 is a real jump but it's done all the time from your current baseline.
