Of course, as much as possible is good. I started late with level 1 (2.5 months before the exam) and since I work full-time, I didnt have time for more then 250 hours.
How I count? I plan my study, and keep track in an excel sheet.
Like you say, I dont think there is a optimal hour of study, study all you can and make sure you get 90% on the “home exams”, to be sure to get ~70% on the real exam.
I also plan to pass all three first attempts…and I agree L2 is much more difficult then L1.
The question I posted was just out of curiosity. To get a feeling for how much efforts people in generally put in for the CFA. Heard something like that the average passer spends 330 hours per exam, the average non-passer around 300.
Cheers and have a good day
