Thanks for the feedback! I'll have to give this some thought. You mean something like a, "X Tries To Get the Next Note?". I could add it as an option.

I think this suggestion you took in an earlier subthread solves GP's problem as well: https://news.ycombinator.com/item?id=46558500

Is that teaching a bad habit though? Is it one of those things where's importantly to be confidently wrong or right?

One of the important keys in learning is engagement. If you frustrate the student preventing them from progressing at their own rhythm they will disengage, losing interest in what you are teaching.

Both things can be true though, right?

Maybe it just needs to reset faster or maybe start more gradually so you can build up muscle memory of intervals.
