Amenophyckxs said...Just my thoughts on the matter though, who knows....That makes a lot of sense. Thank you for elaborating. =)
I don't see KW as a race since there's no new levels to unlock if you do well on your reviews!
The long tail of reviews should go on for as long as necessary to ensure the items are in your long term memory. I'd prefer 12months of WK + KW for 1 vocab item, instead of 6months of WK + KW (at same time) for 1 vocab item.
Logically it seems more sensible to separate the two srs timings (full WK then full KW), but that may not be the truth of the matter :P
It's possible that both at once or slightly delayed (start KW when item is at WK enlightened?) is a successful combo.
I've settled on the simplest, least interfering option as likely to be the most effective long-term strategy (in my opinion/experience).
Knowing 2x items in a year is less important than knowing 1x items for years.
And... since we intend to add / allow users to add more vocab to KW, I intend to use it for years (and continue making it better slowly over time).
