I would like to ask if you could also post the criteria and actual way of how the counter works. I mean the time spent, shown on Internet Time, is not really the exact time spent. I heard it's a complex thing, but still, students should know how it works and what they need to rake those hours in. I have done all there was to do in lessons we have covered at school, do I still get the timer running even if I am just browsing the previous Units? How does it all work? Thanx!

That pretty much sums it up for me, thank you!
