Let’s say I have 15 minutes to spare, and spend them all on (continuous) study in IKnow. At best, 13 of them will be actual study, with as little as 10-11 sometimes.
Why? because of the loading time. And I’m always on max items/course(20) at once, and there are definitely others who stick to 5items/rep, or the traditional 10. It does sound a bit silly to complaining about one lost minute out of 10, but multiply it and you get about 10 hours for every 100 lost. And that’s ignoring the fact that the course division makes it oh so easy to space out and distract yourself with internet in between reps.
