Yes, but that's pretty easily solvable by adding a button saying "I know this word, skip the learning phase" and then having a second button during the later SRS review phase saying "I really, really know this and never want to review it again.".

My opinion is that you shouldn't put in generative too early, that's just frustrating. It's like having a Lvl 80 Mob in the beginners area in WOW. Not good design.

I think finding an automated way to determine which tests to show the user should be done after all the tests are put in and work correctly.
