When you study, you want to simulate test-taking conditions as much as possible. When you do sets of 15, are you varying the difficulty of the questions? It might be good to do think of the set of 15 as three mini-sets of 5, where each mini-set is of a different difficulty level. Mix these up and it'll feel a lot more like the real thing.
Also, sets of 15 are helpful, but it sounds like stamina is an issue for you. Consider doing sets of 30 every now and then to see if you can keep your timing under control and your mind sharp. Remember that the real thing has 41 questions on the verbal side... that's a lot more than 15! Combine these verbal sets with quant sets as well (first quant, then verbal as on the official exam).
Lastly, consider revising your timing strategy. The 1.82 comes from dividing 75 by 41, right? Instead, budget less time for SC (say, 1:00 to 1:15) and more time for CR (2:00 to 2:15). You'll get more bank for buck with this kind of allocation, so consider it. For RC, spend 3-4 minutes reading/taking notes and 1 minute per question. It sounds like RC is the question type that requires the most attention from you as far as timing, so invest time and energy into making an RC strategy that works for you and is time-efficient.
Good luck with your studying!
