I usually end up BRing next day. It just depends on how I'm feeling. My priority is maximizing mental clarity, and PTs are obviously really draining. If you can stay fresh and sharp after a PT, go for it. If you need to hold off to recharge, no worries.
Did just the LG Bundle for a couple weeks, then jumped right into PTs and then after about 5 or so I started really letting the analytics guide my prep from there to shore up any weaknesses.
If you're missing more than 5 per LR section I think you have some issues with your fundamentals and I would take some time to go back through the logic lessons as well as any question types that you really struggle with based on the analytics.
First make sure your LG is on lock, like 0-2 wrong on average. Just start PTing and build some analytics. Then after 5-10 PTs go back and work on your weak areas.
