I'm currently using the ipad mini and I'm manually adding words. When I reach the point that I have to do only roughly twenty revisions, I add, say, ten new words. These appear, however, all in one row. I'd prefer them to rather be equally distributed around my normal revisions. I there anything I can do about it? If I change to add words (normal/fast) I have the feeling that too many words are added on one day. I have set my limit to 10-15 words a day. Cheers!

Occasionally I get other words pop up between new words. Usually they are all in a row. Which makes sense as they will all have the same time until they need to be reviewed. I guess you could spread them out, by adding a word then doing some reviews e.t.c. Instead of adding them all in one go.

If you get a lot of new words, the system will try to spread them out, but it's configured such that it doesn't think ten new words are a lot, so it doesn't spread them. I think if you want to manually add in those quantities such that the new reviews are spread out, 夏本's suggestion is good: manually add fewer words per batch over a few batches.

Alright, cheers!
Will do it as recommended.
Thank you guys!
