Of course everyone’s goals, time available and general learning abilities are different. I cannot say for yourself. You can adjust your speed as needed. There is bunch of topics discussing slow-down/speed up strategies (one need to use userscripts for latter).
Common things people say:
*it’s good to compete all reviews each day
*try to honor the first and second SRS intervals for memory reinforcement (review in 4 hours, and later in 8 hours)
*if you need to take a break, vacation mode will save you a headache later
*the most difficult thing in general is to return after big break, so try not to go on such a break. My personal take is slow and steady.
Here is a good guide, but it’s one from very speedy user, so check other Level 60 topics to have fuller picture:
