I am struggling with understanding this with retention rates. I have a personal goal of always be above 94% in total. When I start each day with my first sessions and have many items marked as so so I might be dropping down to less than 90%. However, after an hour or so it starts to sharply go up. I have today studied for almost 2 skritter hours and have a total retention rate for today of 97,8% ( it is possible that a recalculation today have impacted the rate but that too is strange since other days have not been better). I am not sure how this is calculated but it seems very odd to me since i have had a bad day with plenty of so so items. I thought that so so where treated almost as failed and hence there should be a low rate for this. Is it possible to give some clarity in how the retention rate is calculated for different items? Is the weight the same for a tone as for a writing e.g. This with time is the the thing that puzzles me the most. It seems to be always the same, add more time and your rate will go up. This is the situation even when i feel that i have the same number of fails or so so all day long.
