That's a question we individually have to adjust to. To me it's not a matter of time I spent on SFI it's the best time to spend in SFI.
It doesn't really matter if you spent countless hours working your SFI you're just going to work yourself to death. It's a scientific fact that everyone of us have a peak time during the day. That's when your senses are most alert. For example, there are people are more alert during the morning and some during night time.
Find your peak time and work your SFI within that time. You'll find yourself more productive and get more things done.
