Difference between practice from unit and from vocabulary

I can't be 100% sure but it seems that algorithms of choosing sentences given in a practice session launched from a unit and from the vocabulary section of that unit are different.

When I hit "Practice" here: http://duolingo.com/#/skill/de/Verbs:-Present-2 I get a lot of words learnt long ago. They are even shown with full progressbars as they are strong. New words are rarer.

When I click the "View full vocabulary from Verbs: Present 2" link and hit "Practice weakest words" here: http://duolingo.com/#/vocab/e43e0acd1f6d7701daea6702196a9f88, I get just what I need: a good practice of words that are really new to me.

Is this difference intended? Maybe the "Practice" button in a unit does not focus the practice session on new words but on all the words including old ones? Or maybe it's all in my head :)

By the way, there seems to be a bug with vocabulary practice: http://duolingo.com/#/comment/206640. If not for that, I would use vocabulary practice all the time because I need to train new words and not the old ones.

I'm getting more and more annoyed by this problem :-( I am sick of "spielen" in every practice. I never peek on it and I never make mistakes on it. Why do I get it all the time?! I want to practice new words before moving on, but I get "spielen" and "laufen" again and again.
