When I learn or review relatively short vocab list, such as a CPod list, I am very often requested to review items which are "not due (10%)". (In many cases these are items are reviewed a few seconds ago.) This happens even though the number of items to review is positive. I would rather wait longer for items that are due.

Tweak your study settings? The options are in part in your profile and in part in the list your are studying.

You shouldn't study a single section or very short list if you don't want to see items that are not due. In those cases, the scheduling is biased towards giving you items which you haven't seen in a while rather than items which are due, so that you can go through everything at least once. So to get items that are due, study all of My Words rather than cramming the short lists.

Nick, thank you for your answer. I am not sure I understand. After listening to a CPod podcast, I usually want to study the corresponding vocab list. When I study a new CPod list I very often get "not due" items that I reviewed only seconds ago, even though there are still words in the list that were not displayed even once. (In other words, I would like the bias towards items which I haven't seen in a while, or haven't seen at all, to be even larger.)

范博涵, which study settings are relevant in this case?

Oh. In that case, perhaps the problem is that it's not biased _enough_ in the direction I describe. Try studying single sections of the ChinesePod lists at a time rather than the whole list (two sections together). That should really crank it away from SRS and towards seeing all the items.

swimming, I thought you might be able to influence the behaviour using the last three settings in Profile\Study settings (Target Retention Rate, Add word frequency, Section Movement), but it seems I was wrong about that. See:

In Vocab Lists, after you click on a list, you have the options "Study Mode" and "Pause Adding After Each Section", but it is doubtful these will resolve your issue either.

Shouldn't due items always appear before items that are not due? I can't imagine situations in which I would want something else to happen.

It seems strange to have to learn single sections of ChinesePod lists separately.
The lists are so short to begin with.

I sometimes see items that are not due 0-10% range, often VERY recently studied pop up. I almost never study just a single list, and have hundreds to thousands of items due daily. It seems to be a bug, but it never bothered me much. I will try to report it next time I see it, if that's useful.

Nicki, that can happen sometimes when connectivity is erratic. That's probably what is happening in your case, either on your end or on the server's.

swimming, say that you have a list with 6 words, doing word writings only:

绿色 - 1 day ago, 111% due
红色 - 2 days ago, 110% due
黄色 - 1 year ago, 5% due
大熊猫 - 6 weeks ago, 50% due
孔子 - 5 weeks ago, 100% due
妈妈 - 1 minute ago, 1% due

In normal study mode (like if you studied all of My Words but only had these six items), you would see them in dueness order, except that the words with 色 would have to have a certain minimum spacing, because the shared characters can't be loaded at the same time. So maybe you'd get 绿色, then 孔子, then 大熊猫, then 妈妈, then 红色, then 孔子, then 大熊猫, then 妈妈, then 黄色.

In list mode, there would be a bias toward the older items, even if they weren't due, so maybe you would see: 孔子, 红色, 大熊猫, 妈妈, 孔子, 绿色, 大熊猫, 妈妈, 黄色.

In section mode, you'd see an even stronger bias toward the older ones: 黄色, 孔子, 大熊猫, 妈妈, 红色, 孔子, 大熊猫, 妈妈, 绿色. In this case, it turns out (due to these complex interactions) that the most-due item, 绿色, is studied last.

May not be too clear, but the point is that when studying small sections and lists, especially if there are many shared characters, that there are many complexities involved which adjust things away from the spaced repetition order.

So is it possible that you are seeing those 10% due items because the items which are due are related to the 4-6 loaded for review?
