I use BishBashBosh after every review session (i.e. 3 times a day); I usually click on the ‘All that stuff’ button, but will use the ‘+ 4 ancient gurus’ once every day or so.
P.S. There was a discussion somewhere about the formula used for the leeches list (which the Self-Study Quiz script uses for the leech-training aspect of the quiz) - it turns out if you get an item wrong enough times (5? 7?) the formula is such that the item can never leave the queue. I had several such items, so stopped using the leech table and the eventually the quiz.
